Free Space Optical (FSO) communication systems provide many benefits for satellite communications, including high data rates and low Size, Weight and Power (SWaP) compared to traditional RF communication systems.Additionally, FSO systems operate without RF emissions and are inherently immune to RF interference and jamming.The narrow optical beams and small Field-of-View of the optical receivers al ...STTR Phase I 2018 Department of DefenseAir Force
SBC: Guidestar Optical Systems, Inc. Topic: AF18AT006
Modern Directed Energy (DE) missions require target engagements at low elevation angles and long ranges.These engagement geometries require propagation through distributed-volume turbulence. To correct for distributed-volume turbulence effects, an estimation of the turbulence along the propagation path is required. Correcting for these image aberrations will improve the quality of the target image ...STTR Phase I 2018 Department of DefenseAir Force
SBC: LONGSHORTWAY INC. Topic: AF15AT35
ABSTRACT: LongShortWay Inc and NorthEastern University propose new feature clustering methods that improve performance of motion imagery classifiers. Developed algorithms will be demonstrated on AFRL Minor Area Motion Imagery (MAMI) data; BENEFIT: Enhanced classifier performance, robust feature selectionSTTR Phase I 2015 Department of DefenseAir Force
SBC: SA PHOTONICS, LLC Topic: AF14AT12
ABSTRACT: We exploit recent advances in magnetoelectric/piezoelectric (ME/PE) composite materials to enable the development of efficient sub-wavelength radio frequency (RF) transmitting antennas. With these materials will be possible to achieve high dielectric permittivity and magnetic permeability, slow electromagnetic propagation and low RF loss tangents. Together, these special properties m ...STTR Phase I 2015 Department of DefenseAir Force
SBC: HYPERCOMP INC Topic: AF14AT07
ABSTRACT: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...STTR Phase I 2015 Department of DefenseAir Force
Intelligent and Multiplexable Ultra-High-Temperature Fiber-Optic Pressure Sensors for Robust Distributed Engine ControlSBC: INTELLIGENT FIBER OPTIC SYSTEMS CORP Topic: AF16AT18
Next-generation intelligent engines will operate at higher temperatures for increased efficiency and will migrate from centralized to distributed control. There is critical need for sensors for operation at ultra-high temperatures (3000F). Conven...STTR Phase I 2016 Department of DefenseAir Force
SBC: Metacomp Technologies, Inc. Topic: AF16AT14
The ability of Large-eddy simulation (LES) techniques to accurately predict combustion instabilities and the onset of lean blow-out is not yet firmly established, especially in realistic operating conditions. A number of modeling choices play an importan...STTR Phase I 2016 Department of DefenseAir Force
Laser and Rapid-thermal Crystalization of GeSn and SiGeSn layers for IR detectors and Si-based OE devicesSBC: FREEDOM PHOTONICS LLC Topic: AF16AT28
Advanced infrared imaging techniques are of great interest but associated high costs of III-V and II-VI SWIR and MWIR materials prohibit their widespread deployment and integration with other optoelectronic devices. Freedom Photonics and its team partner...STTR Phase I 2016 Department of DefenseAir Force
SBC: FREEDOM PHOTONICS LLC Topic: AF16AT30
allowing the sensitive RF front-end to be located away from the now more compact phased array antenna. We are proposing a rugged photonic integrated spatial division multiplexing RF link for phased array system with low cost, size, weight and power cons...STTR Phase I 2016 Department of DefenseAir Force
SBC: DYNAFLOW, INC Topic: AF17BT001
The widespread use of Aqueous Film Forming Foams (AFFF) at DOD facilities for firefighting, training, and fire suppression systems has resulted in numerous contamination sites. The perfluoroalkyl (PFA) compounds used in the AFFF, such as perfluoroalkyl sulfonates (PFOS) and perfluoroalkyl carboxylic acids (PFOA) are extremely stable in the environment and have been shown to be resistant to typical ...STTR Phase I 2018 Department of DefenseAir Force
