Tunable Diode Laser Absorption Spectroscopy Verification Analysis for Use in the Combustion Optimization and Analysis Laser Laboratory
The AFIT Combustion Optimization and Analysis Laser (COAL) laboratory has state-of-the-art laser diagnostic capability for combustion process. The research for this thesis served to enhance the COAL lab's capability. Currently, there are no known commercially available tunable diode lasers that produce Ultra-Violet radiation required for this analysis. Sum-frequency generation at 313.5 nm was utilized for high speed OH absorption and temperature measurements at a rate of 2kHz. The Tunable Diode Laser Absorption Spectroscopy system was validated by comparison with theoretical and well characterized experimental data by operating the system over a wide range of conditions for an H2 laminar flame produced by a Hencken burner. The TDLAS system was able to perform at reasonable accuracy. After validation, the system was also characterized for a turbulent environment by comparing turbulent and flame structure theory with results obtained from a C2H4/N2 jet flame. The testing was also conducted for a range of conditions and produced reasonable results. The accuracy of the system is sufficient for utilization in investigating behavior in a turbulent, combusting environment.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Controlling Fringe Sensitivity of Electro-Optic Holography Systems Using Laser Diode Current Modulation
Electro-Optic Holography (EOH) is a non-intrusive, laser-based, displacement measurement technique capable of static and dynamic displacement measurements. EOH is an optical interference technique in which fringe patterns that represent displacement contour maps are generated. At excessively large displacements the fringe density may be so great that individual fringes are not resolvable using typical EOH techniques. This thesis focuses on the development and implementation of a method for controlling the sensitivity of the EOH system. This method is known as Frequency Translated Electro-Optic Holography (FTEOH). It was determined that by modulating the current source of the laser diode at integer multiples of the object vibration, the fringe pattern is governed by higher order Bessel function of the first kind and the number of fringes that represent a given displacement can be controlled. The reduction of fringes is theoretically unlimited but physically limited by the frequency bandwidth of the signal generator, providing modulation to the laser diode. Although this research technique has been verified theoretically and experimentally in this thesis, due to the current laser diode capabilities it is a tedious and time consuming process to acquire data using the FTEOH technique.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Retroreflector for Photonic Doppler Velocimetry
In order to meet the goals of the Department of Defense (DoD) for smaller and more accurate weapons, the Munitions Directorate of the Air Force Research Laboratory (AFRL/RW) has numerous projects investigating the miniaturization of weapons and munition fuze components. One of these efforts is to characterize the performance of small detonators. The velocity of the flyer, the key component needed to initiate a detonation sequence, can be measured using a photonic Doppler velocimeter (PDV). The purpose of this research was to develop a microelectromechanical system (MEMS) device that would act as an optimal retroreflective surface for the PDV. Two MEMS solutions were explored: one using the PolyMUMPsTM fabrication process and one in-house fabrication design using silicon on insulator (SOI) wafers.

Range Precision of LADAR Systems
A key application of Laser Detection and Ranging (LADAR) systems is measurement of range to a target. Many modern LADAR systems are capable of transmitting laser pulses that are less than a few nanoseconds in duration. These short-duration pulses provide excellent range precision. However, randomness in the detected laser signals places limits on the precision. The goal of this dissertation is to quantify the range precision limits of LADAR systems. The randomness in the time between photon arrivals, which is called shot noise, is discussed in depth. System-dependent noise sources such as dark current and detector gain variation are considered. The e ect of scene-dependent parameters including background light, target obscuration, and target orientation is also discussed. Finally, noise mitigation strategies such as pulse averaging and gain equalization are described and tested on simulated and real LADAR data.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Test and Evaluation Methods for Human-Machine Interfaces of Automated Vehicles II
With the introduction of automated driving systems (ADSs) and advanced driver assistance systems, the communication of the driver's responsibilities and the AD's capabilities has become an important topic in recent years. For example, partially automated driving (SAE L2) systems need to be able to communicate that the driver is still fully responsible for driving safety, whereas higher levels of vehicle automation need to be able to communicate that the driver has to act as a fallback-ready user in case of system limits and malfunctions (SAE L3). During the same trip, different levels of automation might be available to the driver, making it even more crucial that the driving mode is efficiently displayed. These developments require new, standardized tests and evaluating methods for in-vehicle Human-Machine Interfaces (HMIs).

Efficient GPS Position Determination Algorithms
This research is aimed at improving the state of the art of GPS algorithms, namely, the development of a closed-form positioning algorithm for a stand-alone user and the development of a novel differential GPS algorithm for a network of users. The stand-alone user GPS algorithm is a direct, closed-form, and efficient new position determination algorithm that exploits the closed-form solution of the GPS trilateration equations and works in the presence of pseudorange measurement noise for an arbitrary number of satellites in view. A two-step GPS position determination algorithm is derived which entails the solution of a linear regression and updates the solution based on one nonlinear measurement equation. In this algorithm, only two or three iterations are required as opposed to five iterations that are normally required in the standard Iterative Least Squares (ILS) algorithm currently used. The mathematically derived stochastic model-based solution algorithm for the GPS pseudorange equations is also assessed and compared to the conventional ILS algorithm. Good estimation performance is achieved, even under high Geometric Dilution of Precision (GDOP) conditions. The novel differential GPS algorithm for a network of users that has been developed in this research uses a Kinematic Differential Global Positioning System (KDGPS) approach. A network of mobile receivers is considered, one of which will be designated the 'reference station' which will have known position and velocity information at the beginning of the time interval being examined. The measurement situation on hand is properly modeled, and a centralized estimation algorithm processing several epochs of data is developed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Optical Flow-Based Odometry for Underground Tunnel Exploration
As military operations in degraded or GPS-denied environments continue to increase in frequency and importance, there is an increased necessity to be able to determine precision location within these environments. Furthermore, authorities are finding a record number of tunnels along the U.S.-Mexico border; therefore, underground tunnel characterization is becoming a high priority for U.S. Homeland Security as well. This thesis investigates the performance of a new image registration technique based on a two camera optical- flow configuration using phase correlation techniques. These techniques differ from other image based navigation methods but present a viable alternative increasing autonomy and answering the tunnel based navigation problem.

Fabrication Techniques for Micro-Optical Device Arrays
Micro-optical devices are vital components of conventional military data storage, sensor, and communication systems. Two types of micro-optical device arrays exist: individually addressable and matrix addressable. The matrix addressable array has a drastically reduced number of metal lines and can potentially be fabricated into large, dense (over 1k elements) arrays. Such arrays are expected to enable the development of extremely high bandwidth optical interconnect systems for future military applications including optical computing and short-haul fiber optical communication systems. I investigate new fabrication techniques for the assembly of dense matrix-addressed arrays of micro-optical devices such as vertical-cavity surface-emitting lasers. Using a micro-electro-mechanical systems (MEMS) foundry process, I design a test chip that consists of a variety of array configurations to explore possible assembly techniques. I also design a new photolithographic mask set based on assembly by flip-chip bonding and fluidic self-assembly techniques.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Tunable Diode Laser Absorption Spectroscopy Verification Analysis for Use in the Combustion Optimization and Analysis Laser Laboratory
The AFIT Combustion Optimization and Analysis Laser (COAL) laboratory has state-of-the-art laser diagnostic capability for combustion process. The research for this thesis served to enhance the COAL lab's capability. Currently, there are no known commercially available tunable diode lasers that produce Ultra-Violet radiation required for this analysis. Sum-frequency generation at 313.5 nm was utilized for high speed OH absorption and temperature measurements at a rate of 2kHz. The Tunable Diode Laser Absorption Spectroscopy system was validated by comparison with theoretical and well characterized experimental data by operating the system over a wide range of conditions for an H2 laminar flame produced by a Hencken burner. The TDLAS system was able to perform at reasonable accuracy. After validation, the system was also characterized for a turbulent environment by comparing turbulent and flame structure theory with results obtained from a C2H4/N2 jet flame. The testing was also conducted for a range of conditions and produced reasonable results. The accuracy of the system is sufficient for utilization in investigating behavior in a turbulent, combusting environment.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Utilizing Near-Field Measurements to Characterize Far-Field Radar Signatures
The increased need for stealth aircraft requires an on-site Far-Field (FF) Radar Cross-Section (RCS) measurement process. Conducting these measurements in on-site Near-Field (NF) monostatic facilities results in significantsavings for manufacturers and acquisition programs.How-ever, NF measurements are not directly extended to a FF RCS. Therefore, a large target Near-Field to Far-Field Transformation (NFFFT) is needed for RCS measurements. One approach requires an Inverse Synthetic Aperture Radar (ISAR) process to create accurate scattering maps. The focus of this work is the development of accurate NF scattering maps generated by a monostatic ISAR process.As a first look, the process is isolated to a simulated environment to avoid the uncontrollable effects ofrealmeasurement environments.The simulation begins witha NF Synthetic Target Generator (STG) which approximates a target using scattering centers illuminated by spherical electromagnetic waves to approximating NF scattering. The resulting NF In-phase and Quadrature (IQ) data is used in a 'Trapezoidal' ISAR process to create spatially distorted images that are accurately corrected within the ISAR process resolution using a newly developed NF correction. The resulting spatially accurate ISAR images do not complete the NFFFT. However, accurate scattering maps are essential for process development.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Using Multiple MEMS IMUs to Form a Distributed Inertial Measurement Unit
MEMS IMUs are readily available in quantity and have extraordinary advantages over conventional IMUs in size, weight, cost, and power consumption. However, the poor performance of MEMS IMUs limits their use in more demanding military applications. It is desired to use multiple distributed MEMS IMUs to simulate the performance of a single, more costly IMU, using the theory behind Gyro-Free IMUs. A Gyro-Free IMU (GF-IMU) uses a configuration of accelerometers only to measure the three accelerations and three angular rotations of a rigid body in 3-D space. Theoretically, almost any configuration of six distributed accelerometers yields sufficient measurements to solve for the translational and angular acceleration. In reality, however, sensor noise corrupts the measurements and good sensor geometry is necessary to obtain an accurate estimate of the translational and angular accelerations. Determining the optimal configuration of accelerometers is an exercise in geometry. This thesis investigates the optimal geometry of an INS constructed of multiple networked IMUs and develops the accompanying mechanization and error equations. Simple simulations are run to test and validate the basic design principles.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Technology Transition
The transition of technologies ensures that our warfighters have the necessary capabilities to fight the ever increasing and changing global threats. Through the investigative research of this study, technology transition best practices were taken from Department of Defense (DOD) publications, Air Force Instructions (AFIs), and industry. The purpose of this study was to gain an understating on what extent the Air Force Research Laboratories were implementing known technology transition best practices. In examining the use of technology transition best practices, the research provides insight into how technologies are transitioned from AFRL to the acquisition community. This study relies on the perspectives and knowledge of program managers within AFRL. Data analysis along with an extensive literature review led to recommendations such as: an implementation of a technology transition team, co-locating AFRL program managers in program offices; and program management training for managers in the S and T community. It was revealed that only some aspects of technology transition best practices were being implemented. It was also discovered that technology transition involves multiple organizations for technologies to be transitioned. Based on the data collected, it was found that the program manager needs multiple resources and the right knowledge to facilitate technology transition.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Bio-Inspired Approaches-a Leverage for Robotics
The field of bio-inspired approaches (also known as biomimetics or biomimicry) is a design approach in which a product or process is inspired by elements of nature, such as plants or animals. Bio-inspired approaches serve as inspiration and motivation for many engineers and designers in terms of efforts to identify unexpected solutions to problems. These approaches have made great inroads in the aerospace, marine, and automotive industries. The domains of bio-inspiration and bio-mimetics have also been the focus of a number of studies in the field of robotics. There are several examples of their use in the literature, including their implementation in snake-type robots for underwater inspection or in worm-type systems for industrial pipeline inspections. This Special Issue compiles and presents recent advancements in the domain of bio-inspired robotics and their potential applications in industry. This will help researchers from all communities understand the relevance of bio-inspiration in robotics and serve as a platform for the application of these cutting-edge approaches in other fields.
