ABSTRACT:
An optical scanning system (10) is disclosed for scanning a wide incoming field of view of at least 60 degrees. The system (10) incorporates two flat mirrors (12,26) which rotate about two axes (20,28). The motion of the two mirrors is synchronized. The resulting scanned image is directed onto a sensor (54) with minimal rotation and distortion of the image.
