Concentric sampling - sensor system with ultra wide angle - field of vision of

摘要

A very compact, high numerical aperture, high resolution, ultra-wide field of view concentric scanning optical sensor. The concentric scanning optical sensor includes a scanning half ball lens having a flat reflective rear surface, outer and inner shell lenses, and a linear focal surface array. The outer shell lens and linear inner shell lens are concentrically disposed about the center of the scanning half ball lens. The linear focal surface array is disposed along a focal surface of the inner shell lens. The scanning optical sensor may also use a full spherical ball with multiple reflecting surfaces to allow for multiple facet scanning.
