SBC: TAU TECHNOLOGIES LLC Topic: AF19AT005
We propose a three-dimensional imaging approach based on digital holography. Our approach is based on frequency diversity using a single chirped pulse instead of a train of pulses with different frequencies. Our approach promises to mitigate most of the issues limiting the performance of current methods and offer additional enabling capabilities that will improve target identification and tracking ...STTR Phase I 2019 Department of DefenseAir Force
SBC: TAU TECHNOLOGIES LLC Topic: AF19AT006
Tau Technologies is teaming with Dr. David Voelz and his research group at New Mexico State University (NMSU) to propose â€œVibration Imaging for the characterization of extended non-cooperative targetsâ€�, which employs dual-pulses in two different variations for vibration imaging in order to characterize non-cooperative targets at extended standoffs. One method is based on double-pulse ...STTR Phase I 2019 Department of DefenseAir Force
SBC: TAU TECHNOLOGIES LLC Topic: AF19AT007
Efficient design, build, and test of an HEL system leverages modeling and simulation (M&S) to reduce cost and increase robustness. Designers use models to explore parameter variations and to estimate performance in conditions which cannot be tested due to physical or financial constraints. This provides significant savings in cost and time. Because live testing is so expensive, it is best used as ...STTR Phase I 2019 Department of DefenseAir Force
SBC: DYNAMIC SYSTEMS & RESEARCH CORP Topic: AF18AT012
The development and implementation of new damage morphology models for concrete materials is critical to understanding their dynamic behavior during severe shock loading environments. Current constitutive models of conventional strength concretes do not accurately represent the behavioral characteristics of new ultra-high strength concretes because of differences in damage mechanisms during failur ...STTR Phase II 2019 Department of DefenseAir Force
SBC: MZA ASSOCIATES CORP Topic: AF18BT004
Wave-optics simulations are critical tools for analysis of laser directed energy systems. The primary method for conducting these simulations is to evaluate the Fresnel diffraction integral using the angular spectrum method based on the fast Fourier transform (FFT). While FFTs are considered computationally efficient, their use in the Fresnel integral results in difficult grid constraints includin ...STTR Phase I 2019 Department of DefenseAir Force
SBC: MZA ASSOCIATES CORP Topic: AF19AT005
Target tracking and aimpoint maintenance are critical functions within a laser directed energy system. Traditionally, the optical sensor is a conventional camera viewing an actively illuminated target. In the absence of turbulence, it is still difficult to point the laser weapon to a specific hit spot when there are no features in the required direction. Further, atmospheric turbulence scintillate ...STTR Phase I 2019 Department of DefenseAir Force
SBC: MZA ASSOCIATES CORP Topic: AF17AT008
MZA partnered with the Michigan Technological University (MTU) proposes development and testing of key components for our unified Atmospheric Refractivity and Turbulence Sensor (ARTS.) Software upgrades will be made to MZAâ€™s DELTA-Sky sensor to enable atmospheric refraction measurements in addition to existing turbulence profiling. The illuminator assembly to implement the ARTS probe laser ...STTR Phase II 2019 Department of DefenseAir Force
SBC: VULCAN WIRELESS, INC. Topic: AF18AT010
This proposal will outline a bi-directional software defined Free Space Optics (FSO) laser communications testbed with flexible optical elements and reprogrammable waveform and signal processing elements. Vulcan Wireless Inc. currently manufacturers a 1550nm, eye safe, software defined Laser Communications Testbed MD-LC-1 and will use this as a basis for the Phase 1 effort. We will also be teaming ...STTR Phase I 2019 Department of DefenseAir Force
Photonic Integrated Circuit (PIC)-Enabled Chip-Scale Atomic Devices (CSAD) for Precision Navigation and Timing (PNT) ApplicationsSBC: INTELLIGENT FIBER OPTIC SYSTEMS CORP Topic: AF19BT001
Sensors based on chip-scale atomic devices (CSADs) offer portability, manufacturability, and high performance for precision navigation and timing (PNT) missions. Key systems for PNT including atom interferometric gyroscopes (AIG) and atomic clocks. Ongoing advances and innovations in photonic integrated circuits (PICs) are directly relevant to CSADs. Different material bases have been used in PICs ...STTR Phase I 2019 Department of DefenseAir Force
SBC: ROCHESTER SCIENTIFIC LLC Topic: AF19AT008
Large ground-based telescopes require adaptive optics (AO) to correct for distortions introduced by atmospheric turbulence. In order to function, the AO system must track a bright point source. Although a natural star may be used, full sky coverage requires an artificial beacon created with a laser. The most common type of laser guide star (LGS) employs the mesospheric layer of sodium atoms at an ...STTR Phase I 2019 Department of DefenseAir Force
