Abstract

An experimental examination of the suitability of using a CCD imaging sensor for space lasercom applications was conducted. A specialized CCD camera capable of operating in high rate partial frame mode for tracking as well as normal rate full frame mode for acquisition was built. CCD pixel rate is 7.5 MHz. A flash A/D digitizes the pixel signals and inputs them to a 30 MIPS digital signal processor which processes the input data between pixels. The processor inputs the pixel magnitude, compares it to the previous brightest pixel in the frame, saves it to memory, remembers its location and magnitude if it is brighter than the previous brightest pixel, and then inputs the next pixel.
