Abstract
An infrared scene projector is described in this paper which based on light down conversion. The film transducer is the key device of the projector which is a free standing substrate and coated on one side with an absorbing optical black. The optical black coating absorbs the visible light and emits the infrared light. The emission spectrum is similar with the blackbody. The single pixel which is 25×25μm in sizes and 35um at intervals in a film transducer is realized by MEMS technology. The array size of the film transducer is more than 1024×1024 in a transducer of 76.2mm (3 inch) diameter. Illuminated by a visible light projector with different intensities, the gray scale is more than 200 and the equivalent black body temperature of the transducer could be varied in the range of 293K to 573K.
