To satisfy unmet military needs for multimode day/night digital image sensors, Voxtel is developing a high-dynamic-range visible-sensitive and near-infrared-sensitive single-photon avalanche diode (SPAD) digital imager with efficient photon detection, hi...

Voice phishing ("vishing") is an increasingly serious threat that cost victims over $46 billion in 2016. Attackers pose as trusted callers using impersonation, voice mimicry, speech synthesis, voice conversion, Caller ID spoofing, and other techniques. Once victims trust the caller, the perpetrator can engage in fraudulent and criminal activities leading to financial losses and security breaches. ...

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 ...

As the human population grows, it is critical to decrease consumption of materials from the planet and its ecosphere. The world adds 70 million people annually. The UN expects the population to grow to over 9 billion 2050. Climate change, soil degradation, unstable water supply all reduce the ability of traditional farming to satisfy food needs. Population increase and scarcity of resources and fo ...

Group 2-3 UAS engines have low mean time between overhauls (MTBOs), often with as little as 200-400 hours before maintenance must be conducted.This leads to significant maintenance cost and logistics tail for deployed operations.Two-stroke piston and rotary engines for Group 2-3 platforms have common maintenance drivers such as carbon fouling, and wear of cylinders, housings and bearings.Phase I r ...

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 ...
