摘要:
An optical system for illuminating and viewing a target (15) in which an illumination element (16) and a receiving element (13) are disposed behind a single optical window (14), and which obtains data essentially free of backscatter and stray light. The optical window (14) is configure such that is defines a shape having at least one focal curve, i.e., an ellipsoid shape dome. The illumination element (16) and the receiving element (13) are geometrically positioned on the focal curve plane or in proximity of the focal curve plane, such that, when illuminating, rays from the illumination element internally reflected from the optical window (14) will not incident on the receiving element (13).
