ABSTRACT:
A system for wavefront aberration reduction of an incident optical beam. The system includes a spatial light modulator (SLM) for receiving the incident optical beam and forming an output optical beam. The output beam is aberration-reduced compared to the incident beam. An interferometer receives a portion of the output optical beam and generates an interference fringe pattern by introducing a phase shift to one part of the portion of the output optical beam, the interference fringe pattern being applied to the SLM. The interference fringe pattern is representative of the wavefront error of the incident optical beam and the interference fringe pattern activates the SLM such that the SLM performs wavefront error correction on the output optical beam.
