Abstract
A lens-sphere optical system for use in a low resolution, very wide angle optical sensor system for viewing incident energy from a scene of interest. A lens-sphere forms an output image of the scene of interest on a spherical surface. Apparatus for optically filtering the lens-sphere blocks incident energy outside of a predetermined range of incident angles. Apparatus for detecting the optically filtered output image is provided.
