ABSTRACT:
A device for providing scan conversion, integration and parallel to serial conversion in one modular element which comprises an array of infrared detectors, amplifiers and LEDs, with said LEDs optically coupled to a CCD sensor which provides an output which may be utilized for image reconstruction. A feed back gain channel connected to the output of said sensor serves to provide a reference which controls the steady state amplitude of all the LEDs thereby stabilizing the LED array.
