Abstract

Efforts to produce a fiber optic based high spatial resolution (4 X 10⁶ pixels/in²) infrared (IR) scene projector for background scene applications are described. Light from a source scene is transmitted by total internal reflection to thin film optical black body cavities at the ends of the fiber elements and converted to IR radiation. The design of the optical thin film black body cavity allows flexibility to tune both source and output characteristics for the scene projector and tailor in-band emissivities to values greater than 0.9. Fiber elements are micromachined into the optic to provide thermal isolation between scene pixels and minimize thermal cross talk. The materials and processes being investigated are discussed with respect to thermal modeling results which direct design considerations. Examples of IR images produced by this approach are presented with discussions of future plans.
