In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

Conversion of highly stable optical clocks into electrical clocks through photodetection introduces excess phase noise and degrades the frequency stability by two to three orders of magnitude.

This proposal responds to DOT topic 081-PH2 "Hazardous Materials (Using Handheld Devices to Assist in Emergency Response to Hazardous Materials Incidents)." The significant innovation in this project involves extending cutting edge tools developed to enhance situation awareness among first responders with appropriate hazmat and traffic information to create a framework for interperting traffic re ...

Voxtel proposes to develop fiber-coupled near-infrared avalanche photodiode (APD) receivers with photon detection efficiency (PDE) and dark count rate (DCR) with more than two orders of magnitude faster maximum count rate (MCR) than Geiger-mode APDs, which are constrained by a fundamental tradeoff between DCR and MCR: if the APD is cooled to reduce DCR, then its dead time must increase to avoid af ...
