Paper Abstract

Display flicker has been an inherent characteristic of 3 to 5 micron lead selenide Forward Looking Infrared (FLIR) systems because the detector time constant ultimately limits the mechanical scan rate. In some systems, flicker has been reduced by increasing the frame rate from 15 to 30 frames per second (FPS); however, objectionable flicker is still apparent at the display edges due to the triangular scan used. This paper presents a digital scan converter technique which produces a completely flicker free display while maintaining the 15 FPS mechanical scan system rate. The system also enables a stop-action mode of display.
