Optical system
First Claim
1. An optical system comprising an illumination element and a receiving means, the illumination element and the receiving means disposed behind a single optical window, wherein:
- said optical window is configured such that it defines a shape having a focal curve; and
wherein said illumination element and said receiving means are positioned in proximity of a focal curve plane of said focal curve, such that, when illuminating, rays from the illumination element, that are internally reflected from the optical window, will not be incident on the receiving means.

Abstract
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).
