Abstract
The design of an alignment-detection system that uses off-axis diffractive elements and photodetectors is presented. The system was developed to detect the real-time misalignment of an array of optical beams as they pass through a microchannel relay. The design of this scheme is presented along with experimental results obtained from a prototype detection system. © 1998 Optical Society of America.
