Micro Solid State Low Light Level Camera

There is a distinct need to replace the current Gen III image intensifier imaging system with a solid state low light level camera. Fairchild Imaging has been working (SBIR A04-116) on an innovative hybrid CCD/ CMOS approach that combines the best of CCD imaging characteristics (high quantum efficiency, low dark current, excellent uniformity and low cross talk) with the high speed, low power, and ultra-low read noise of the active pixel CMOS readout technology via indium bumps. To date we have demonstrated excellent imagery from full day light down to quarter moon light level performance with acceptable MRC performance. Additional technology enhancements such as modifications to the serial shift register on the CCD, a ROIC designed on 0.18um design rules and changes to the indium bump process will improve MTF and SNR as well as reduce read noise and improve the overall performance of the camera. With the implementation of these performance enhancements to the existing low light level camera expect to see a solid state low light level imager with comparable or better Gen III performance.
