Compensation Electronics For Staring Focal Plane Arrays
Abstract
A system which provides complete offset and gain correction to the output of a hybrid (HCT/CCD) staring focal plane has been developed. This system provides high speed, real time compensation using custom processing electronics at the CCD output. A microprocessor controls the operation of the electronics and allows the user to implement any of several operating modes. The compensated output can be displayed on a high speed CRT or on a standard black & white TV monitor to enhance visual resolution. The compensation electronics described here is correcting a 64 x 64 array at pixel rates to 5 MHz. The system can be configured to operate on array sizes up to 256 x 256 at frequencies to 10 MHz as larger arrays and faster analog to digital converters become available.
