ULTRA-WIDE FIELD OF VIEW CONCENTRIC SENSOR SYSTEM

摘要

Very compact, high numerical aperture, high resolution, ultra-wide field of view concentric optical apparatus. The concentric optical apparatus comprises a concentric lens and a focal surface array disposed along a focal surface of the concentric shell outer lens. The optical apparatus may further comprise an image intensifier tube optically coupled to the concentric lens by way of a curved fiber optic relay having an input surface that is concentrically disposed with respect to the concentric lens. The optical apparatus may also comprise a dewar that houses the focal surface array, and wherein the concentric lens comprises a cold stop for the focal surface array.
