Abstract
An apparatus for detecting an incoming laser beam with a photodetector is described. A beam splitter is mounted to receive the incoming laser beam after correction by a wavefront corrector. The beam splitter directs most of the incoming laser beam to the photodetector, but diverts a small portion of the incoming laser beam to a wavefront sensor. A feedback control circuit is configured to control the wavefront corrector to at least partially correct for wavefront distortions detected by the wavefront sensor.
