Phase II will demonstrate the predicted performance improvements in stirling and Gifford-McMahon cryocoolers utilizing a modified parallel plate geometry in the regenerator. This will be accomplished by performing a series of tests in which the dimensionsof the regenerative matrix are varied about the design point to experimentally maximize the cryocooler coefficient of performance. The technique ...

Miniature Software is a new software engineering technology that addresses the many challenges in building real-time code for large pervasive computing applications. These applications will have dozens to thousands of very small processing nodes embeddedinto everything, including within both solid objects and liquid, or attached to any other medium for which sensory information or command and cont ...

Distant high intercept speed (>Mach 7) collisions between missiles produce RF radiation which if detectable by sensors could produce information about the impact and post-impact stages if the radiation signatures were interpretable. But this can onlyoccur with the aid of a physical model that relates the physical states of the radiation source to the resutling radiation at the observer (sensor), ...

Epitaxial Technologies proposes to develop novel material technologies for the realization of broadband components such as oscillators, mixers and preamplifiers. We will achieve this by performing device designs to determine suitable material structures,epitaxial growth and device fabrication processes. We will build on the results of Phase I to design and grow the ideal material structures for RT ...

Genex Technology, Inc (GENEX) has successfully completed a six-month Phase 1 SBIR effort to develop 360-degree panoramic infrared (IR) optical sensor technologies for the missile seekers. This program is sponsored by Ballistic Missile Defense Organization(BMDO) and managed by U.S. Naval Air Warfare Center Weapons Division (NAWCWD China Lake). The wide angle viewing capability is useful as augmen ...

Program Objectives:Laser Fare has two objectives for the proposed Phase II SBIR program. The first involves gathering sufficient statistically significant data, based upon diagnostic examination of a laser trepanned test plate from each of the following sub-contractors:LASAG, Spectra-Physics, Trumpf, Lumonics, and Convergent. Each test plate will include 12,288 laser trepanned holes through an I ...

We will develop and demonstrate Geiger mode APDs using novel materials set, device structure, and circuit for short wavelength (500 - 600 nm) ladar pixels and pixel arrays. Our approach promises extremely low dark count rates at room temperature (1 cps).This quietness allows trade-offs among larger detector area, less cooling (or no cooling), reduced after-pulsing, reduced optical cross talk, high ...

Ultrashort laser pulses have led to the development and demonstration of filamenting lasers, which make possible a vast array of new military and civil applications. These applications result from the filaments' novel ability to channel extremely highfluences through self-focussed channels in the atmosphere. The channels are ionized to electron densities, comparable to those of metals, and the f ...

TDI proposes to develop novel multi-wafer HVPE technology for mass production of large area GaN (and AlGaN/GaN) epitaxial materials. The HVPE technique is a well-established, cost-effective method to grow GaN (and AlGaN) epitaxial layers on sapphire andSiC substrates. Recent advances at TDI have proven HVPE to be a reliable process for fabricating high-quality GaN-based device structures, partic ...
