DESCRIPTION (provided by applicant): The development of a durable, hemocompatible valve prosthesis is the long-term objective of this proposal. While heart valve prostheses have been used successfully since 1960, 10-year survival rates still range from

DESCRIPTION (provided by applicant): Cardiac assist devices are increasingly being used for long term support. As patient survival times increase substantially, long-term management of the patients will increasingly play a role in suitability of these

DESCRIPTION (provided by applicant): Cardiac assist devices are increasingly being used for long term support. As patient survival times increase substantially, device wear-out will increasingly play a role in the clinical management of patients with l

DESCRIPTION (provided by applicant): This Phase I SBIR application seeks support to develop a three dimensional acellular scaffold composed of particulate extracellular matrix (ECM). Products composed of the two dimensional (sheet form) of ECM der

The objective of this Phase I effort is to design and simulate an innovative optical architecture for true, interactive-rate holographic video. Our novel technique takes a contrarian approach to existing multi-view and holographic video systems, which are typically crippled by "jailbar" dark regions, limited viewing zones, and image distortions arising from rendering techniques not intended for m ...

Currently, mid-infrared lasers must be integrated into highly restrictive volumes near the outer surfaces of air platforms. Fiber coupling of mid-infrared lasers would enhance the tactical utility for such devices by enabling the laser to be remotely located from the pointer-tracker. The proposed work will demonstrate the efficient fiber coupling of a mid-infrared semiconductor laser in a low lo ...

This Phase I project proposes an improved laser designator module. This improved module combines diode-pumping with a unique ceramic laser medium and innovative thermal management to provide a system that is small, lightweight, and able to be fully-operational in less than 30 seconds. This design is potentially 5x lighter than current designators, with equivalent optical performance.

The purpose of this program is to develop a compact and efficient ultraviolet laser for use in space-based uv-Raman instruments. The basis for this system will be a diode-pumped neodymium-yttria (Nd:Y2O3) ceramic laser which is frequency-quadrupled to generate uv light at 237nm. The unique combination of a low-cost and robust ceramic laser with efficient 4th harmonic generation will provide an ide ...

DESCRIPTION (provided by applicant): Ultraviolet Resonance Raman Spectroscopy is a powerful technique for detection, identification, and study of a number of chemical and biological species relevant to public health, such as carcinogens and biological

The Navy needs a compact extended range underwater imaging system that can image through > 6 attenuation lengths with 0.25" resolution. Present systems are limited by scattering to ~ 5 attenuation lengths. To meet the need, we propose a compact, adaptive raster scanner, using a doubled Yb fiber laser for the transmitter, a wide field-of-view (FOV) receiver, and an annular APD detector array, ena ...
