This Phase II SBIR project will continue the development of an optical sorter that will be used to estimate drop sizes in sprays. The optical sorter will determine the size of drops in the 0.1 to 10 microns range. Drops in this size range are prevalent in the automobile industry, where the fuel injection pressures have increased tremendously over the past two decades. These newer injectors provide ...

The Air Force rebuilds and tests many aircraft and ground-power generators each year, involving many hours of loaded run-time with dissipative load banks. To improve facility energy efficiency and to have a positive environmental impact, a regenerative ac/dc load bank is proposed to push power from generator testing back to the electric grid. The proposed generator power recapture unit (GPRU) will ...

To enable small drones to navigate by natural nighttime skyglow, Voxtel is developing an ultra-low-leakage, 9-m-pitch, 1080p-format InGaAs photodiode array for compact, lightweight low-light (LL) short-wavelength infrared (SWIR) imaging. In a Phase II effort, the detectors cutoff wavelength will be adjusted to maximize its uncooled signal-to-noise ratio under illumination from the night sky, tradi ...

A high-sensitivity, narrow-field-of-view ladar receiver, optimized for long-range target detection and identification will be developed, characterized, and demonstrated.In Phase I avalanche photodetector (APD) and readout integrated circuit (ROIC) components were tested and validated. In Phase II, the pulse amplification, detection, and timing circuitry will be cast as a fine-pitch 1616-format arr ...

Phase I focused on the selection of a camera and associated optics that would deliver the required imagery along with a concept of operation (CONOP) for the system. Though Phase I isnt complete, preliminary results strongly support the use of a small, zoomable full motion video (FMV) camera for target acquisition paired with an 18MP camera and custom 250mm catadioptric lens to capture still images ...

Voxtel proposes to develop, characterize, and demonstrate a coherent-ladar optimized readout integrated circuit (ROIC) consisting of 40-micron pixel elements, including circuits designed for snapshot-integration operation as short as 250 ns, formatted in a 32 x 32 array capable of readout speeds of 1 M frames per second. In Phase I, the coherent ladar ROIC architecture was developed and specificat ...

Insider threat poses one of the most problematic cyber challenges facing the warfighter today. This threat to Air Force assets is particularly insidiousas trusted individuals have easy access to sensitive and classified information. Galois, Inc. has developed a multi-layered attack inference engine called ADIDRUS, originally designed to help UAVs fight through cyber attacks. ADIDRUS continuously m ...

The main objective of the proposed Phase II project is to leverage the technology of THz generation in resonantly-pumped quasi-phase-matched (QPM) GaAs structures, jointly developed by Stanford University and Microtech Instruments, Inc., and create a compact and power-efficient commercial THz source with a mW-level average power. This source will be continuously or step-tunable in the 0.5-3 THz ra ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

Viscosity and low temperature lubricant characteristics determine turbine engine starting capability, and lubricant motion with respect to the contact surfaces at low ambient temperature. Such low ambient temperatures influence the oil viscosity and also the variation of its curve shape versus the temperature. According to the aforementioned research method, the requirements for accuracy and rel ...
