Abstract

This paper describes a cinematic infrared scene projector based on the use of a thin film of vanadium dioxide as a spatial/temporal modulator in the 8-12 μm wavelength band. Key features of the concept are discussed, including image writing by a scanned laser beam, image erasure by a novel fast cooling and reheating process, and the avoidance of flicker in the output by the use of two optical channels coupled by a rotating framing mirror. Experimental data are given demonstrating the feasibility of operation at (512)² pixels per frame and 30 frames per second.
