ABSTRACT:
An optical system for automatic sorting and inspection machines for providing an improved two dimensional image of a three dimensional object to a camera or a camera-like device is disclosed. The optical system utilizes two spaced apart mirrors for receiving light primarily from different areas of the object to be viewed. Each mirror is positioned to reflect that light toward an optical axis. Positioned between the first and second mirrors are third and fourth mirrors positioned to reflect the light received thereby along the optical axis of the camera system. In this manner the image viewed by the camera will represent two separate views or image portions of the object being viewed, which image portions may or may not overlap as desired. By proper positioning of the mirrors, one can obtain an image of a three dimensional object which includes image portions of minimum distortion which effectively start to reach around the object and therefore not otherwise viewable from the camera position.
