LOWERING COST OF CONGESTIVE HEART FAILURE--PATIENT EDUCA

Not Available A short wavelength infrared (SWIR) camera for high frame rate active tracking and wavefront sensing applications does not presently exist. PixelVision, Inc., a leader in high quantum efficiency, low noise, fast frame imaging systems, proposes development of a SWIR camera that will have the following characteristics: 1) quantum efficiency greater than 50% from 1.06 to 1.4 microns; 2) frame rate in excess of 5kHz; 3) 200x200 element resolution with 16 micron pitch; and 4) read noise less than 50 noise electrons per pixel. The focal plane array readout architecture will be a split frame transfer charge coupled device (CCD). Indium gallium arsenide will be fused to the backside silicon surface of the thinned CCD to provide the active SWIR detection material. A tri-level CCD clock waveform will be used to extract photocarriers from the InGaAs into the CCD charge storage wells and subsequently readout the photocarriers. A conceptual camera design will be developed from modifications to PixelVision's ADAPT3 (sup TM) adaptive optics visible camera.
