A detailed design is proposed to compare one and two mirror, parabolic and aspheric optics to achieve high numerical aperture, high-throughput, sub-micron resolution from 200 to 800 nanometers. An optimization phase will follow for the concept(s) that best satisfy the requirements. Predicted performance will be analyzed for the selected concepts including evaluation of point spread function, mod ...

Confocal microscopy has become the tool of choice for sub-micron imaging, particularly of biological tissues, and is being used as a diagnostic tool in other disciplines as well. Broadband optics are required to collect emitted or scattered light throughout the visible and ultraviolet regions, with minimal spectral and temporal dispersion. The requirement to perform over a broad bandwidth encompas ...

WideGap Technology (WiTech) proposes to develop group-III nitride-based solar blind (

The threat of biological warfare has mandated the need for decontamination methodologies for the military and civilian sectors. Use of chemical agents for decontamination is unfavorable due to their residual nature and potential toxicity to humans and the environment. Both ultraviolet (UV) and x-ray sources have been used individually for bio-decontamination. Currently, there is no combined UV ...

"We propose to develop a target identification system using Time Modulated Ultra-Wide Band (TM-UWB) radars. The prototype hardware will be based on the TM-UWB ASIC chips developed by Time Domain Corporation of Huntsville AL. The only signals transmittedby UWB radars are pulses generated pseudo-randomly in time. The pulses we are currently using are ¿ nanosecond in duration and the energy extend ...

This proposal details an innovative ammunition monitoring system based on Ultra Wide Band (UWB) technology. Our approach is to seamlessly integrate sensitive detection of intruders, communications with friendly forces, and tracking of ammunition units.Sophisticated algorithms for the analysis of radio and radar scans show great potential to limit false alarm rates due to small animals, etc. Due to ...

During this Phase I, we intend to evaluate Ultra Wide Band (UWB) radar for use as a sensor for water content of skeletal muscle. The sensing mechanism is based on the large difference between the dielectric constant of water, and that of the host material. We have clearly demonstrated the feasibility of this approach for sensing of moisture in materials with gross dielectric properties similar to ...

The proposal explains Phase I results, using UWB for sensing muscle water content and lays down the plan for transition in Phase II. Basic operation of our sensor is to inject a train of ultra low power UWB pulses into the body, and coherently measure the reflections with picoseconds time resolution. Our sensor is RF based, and therefore interacts with the electrical properties of the body part un ...
