Paper Abstract

This paper reviews the principles of operation of the electron- beam-addressed membrane-mirror-light-valve-based IR scene projector, and reports on recent advances in it s development for the 3- to 5-micrometers waveband. In particular, recently built projectors with 128 X 128 pixels have exhibited 30-Hz flickerless operation, contrast rations in excess of 100:1 when read out with blackbody sources, and up to 75% readout optical efficiency. A compact high-efficiency readout optical system for coupling the output image into cameras and test systems was also explored.
