Foveated imager providing reduced time-to-threat detection for micro unmanned aerial system

A foveated imager providing a panoramic field of view with simultaneous region of interest optical zoom for use on a micro unmanned aerial vehicle is described. The foveated imager reduces size, weight and power by imaging both wide and telephoto fields onto a single detector. The balance of resolution between panoramic and zoom fields is optimized against the goals of threat detection and identification with a small unmanned aerial system, resulting in a 3X reduction in target identification time compared to conventional systems. A description of the design trades and the evaluation of a prototype electro-optical system are provided.
