The ultimate Virtual Environment system must free the user of const raining hardwire connections to the host computer or telepresence sensors. In addition to wirelessness, the headset must be unobtrusive and deliver a high quality image. We propose a research methodology and development… More

This Phase I research will focus on developing a low power usage chip-based micromachined CC (MMGC) column and sample accumulator. The design of this Innovative miniaturized MMGC will be aimed at reducing the amount of time needed for an analysis. The unique column approach incorporates a stationary… More

We propose a new approach to the fabrication of large, low scatter diffractive optics using a hybrid of existing ¿off-the-shelf¿ methods. Although several techniques are used to make diffractive optics, no single method is currently capable of the large clear aperture size, wavefront accuracy and… More

This Small Business Innovation Research (SBIR) Phase I project proposes to address the need for large highly efficient gratings as essential components of astronomical, spectroscopic, and optical telecommunications equipment. The goal of the proposed research program is to develop a hybrid… More

Recent studies have demonstrated that user error can be reduced when using night vision goggle if the user's field of view and resolution is increased. Efforts to provide a wide viewing field with traditional approaches have led to complex and expensive wide angle or multiple lens/tube designs… More

Diffraction LTD proposes to develop a novel occipital head-lock system to support advanced night vision goggles (NVG) used by Air Force personnel not wearing typical aviation or combat helmet. Phase I efforts will demonstrate the feasibility of a lightweight, direct head mount that maintains… More

The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict… More

Diffraction LTD will develop a multi-spectral battery powered combat ID beacon. Key emitter technologies will include vacuum encapsulated photonic crystals in the MWIR and LWIR spectral bands. In Phase 1, a complete optical, electrical, and mechanical design of the beacon will be produced. A… More

Clip-On Thermal Imagers (COTIs) have greatly increased the utility of night vision goggles (NVGs). Fusion of thermal and image intensified imagery has improved the warfighter's ability to quickly detect and then target or record potential targets and threats. Current generation COTIs are… More

For Phase 2, Diffraction proposes to develop a small, lightweight, low profile, battery powered multi-spectral combat ID beacon. The beacon will output enough energy in the mid wave infrared (MWIR) bands to be visible to nearly all US and allied targetin
