RECORDING AND PROCESSING THERMAL IR IMAGERY

THERMAL IR SCANNER IMAGERY WAS FORMERLY RECORDED DIRECTLY ON FILM, BUT MOST MODERN SCANNERS RECORD ON MAGNETIC TAPE WHICH IS PLAYED BACK ONTO FILM. THE TAPES MAY BE REPLACED TO OBTAIN CORRECT IMAGE SCALE AND OPTIMUM CONTRAST AND DENSITY. THE IMAGERY MAY BE RECTILINEARIZED TO ELIMINATE MARGINAL DISTORTION INHERENT IN SCANNER RECORDING. TYPICAL IMAGERY IRREGULARITIES CAUSED BY AIRCRAFT MOTION, WEATHER, ELECTRONIC NOISE AND PROCESSING PROBLEMS ARE ILLUSTRATED ALONG WITH SUGGESTIONS FOR THEIR PREVENTION. IMAGE ENHANCEMENT METHODS SUCH AS DIGITIZED GRAY SCALE, LEVEL SLICING AND COLOR DISPLAY ARE AIDS TO THE INTERPRETER.
