Abstract
Coherent optical feedback systems always use a pair of tilted mirrors that physically separate the forward path and the feedback path, one of which is at an off-axis position. This paper introduces an on-axis configuration with two parallel mirrors. The application of the system to contrast enhancement and image restoration is presented.
