Controlling millimeter radio frequency waves with optical signals is a requirement for military communications and radar systems. The advances in the past decade have led to photonic sensors and switches that utilize light beams interacting with RF devices. New capabilities extending to higher frequencies and working over multiple frequency bands are possible using a combination of nonlinear op ...

There are currently no fire warning systems in use at ammunition storage areas. This is due to the lack of a detection and warning system that is capable of operation in large areas where there are multiple background sources. Early detection and suppression of fires in hazardous areas can save lives as well as millions of dollars in lost weapons and ammunition. We propose a fire-detection and ...

The Reconfigurable Operator Station Simulator (ROSS) project will provide designers of operator stations for Uninhabited Aerial Vehicles (UAVs) with a rapid prototyping system. In addition, the architecture on which ROSS is based provides a platform on which to build tools that increase the ability of operators to control UAVs and to impart a far greater understanding of the situation to them. T ...

We propose to design and fabricate an optical filter that can be tuned continuously from 1.5 um to 2.5 um with a linewidth less than 1 nm. Our system consists of 2 separate filters that can each be electronically tuned. One provides a large free spectral range, and the other provides a narrow linewidth.

Active noise reduction (ANR) headsets have found a market niche in the hearing protection industry, thereby validating the technology of active noise control for personal applications. This Phase I project will seek to extend the application of personal ANR systems to include specialized headphones which can successfully evaluate hearing acuity in typical clinical environments. To ensure a succe ...
