Paper Abstract

We report the operation of a video-based infrared scene projector which utilizes an electron beam-addressed membrane light modulator, or e-MLM. The projector may be described as a schlieren projector which modulates both the phase and intensity of a readout light beam. In the present work, the readout source was a He-Ne laser and the readout wavelength was 3.39 micrometers . 128 X 128 pixel images were projected at a 30 Hz frame rate, and imaged by an infrared camera. The electrical input to the projector was a standard RS-170 signal provided by a commercial video cassette player. Some of the characteristics of the projector include flickerless framing, 100:1 contrast ratio, and continuous-tone gray scale. This technology is capable of high simulated temperatures and radiance. With further development, the technology should be capable of full NTSC resolution and higher frame rates.
