We introduce a concept and a design for a high-speed, high-temperature infrared (IR) scene projector for midwave and longwave infrared application. Results from this study of carbon nanotube (CNT) material characteristics, along with field emission and electro-thermal modeling show that 2000K effective midwave infrared (MWIR) temperatures can be sustained and projected by this carbon nanotube pixel with little or no spillover to adjacent pixels. The proposed projector utilizes groups of selectively grown nanotube arrays to construct the projector pixel. Pure carbon nanotubes can sustain temperatures as high as 4800K and emit as lambertian blackbodies. The nanotube thermal time constants are on the order of nanoseconds to picoseconds and since the nanotube array consists of individual isolated nanotubes or minimally connected (touching) nanotubes, the entire nanoforest will exhibit the same ultra-fast response. The projected image will be continuous in time as with the microemitter arrays but will be able to project significantly higher temperature, high dynamic range scenes at frame rates far above 400 hertz. The projectors high frame rates, small pixel sizes, and blackbody emittance over the entire infrared region fully supports real-time testing of sensors and may provide considerable size and weight advantages.
