Abstract

A Variable Angle Prism for large field of view spot array alignment with a quad-cell and PID feed-back control loop is investigated. The free-space link consists of two smart pixel planes, interconnected by a simple bulk-lens relay system. Initial studies employ individual VCSELs, detectors and quad-cells to mimic a more fully integrated system. Focus is on the sources of error, including thermal and vibration, and studying the restoration of system performance. Results of the investigation are discussed.
