Active wavefront sensing and wavefront control with SLMs

SPIE Proceedings, 2004
Active systems are becoming more and more prevalent in the the field of optical technology. These systems require not only means of controlling wavefronts but mostly also of sensing wavefronts. This paper shows in four examples how spatial light modulators can be utilized to perform active wavefront sensing and wavefront controlling tasks. The examples

Computer-controlled wavefront corrector

Soviet Journal of Quantum Electronics, 1989
It is shown that an optically controlled liquid-crystal spatial modulator can be used to form a given wavefront when focusing on a line or a plane. Focusing to form a line, a circle, and a square are demonstrated.

Stellar Imager: wavefront control

SPIE Proceedings, 2008
Stellar Imager (SI) is a proposed NASA space-based UV imaging interferometer to resolve the stellar disks of nearby stars. SI would consist of 20 - 30 separate spacecraft flying in formation at the Earth-Sun L2 libration point. Onboard wavefront sensing and control is required to maintain alignment during science observations and after array ...

Modal wavefront control system

Conference on Laser and Electrooptical Systems, 1976
A 9-channel 100-Hz closed-loop modal multidither COAT (Coherent Optical Adaptive Technique) system is described that could be used to improve propagation of a laser beam through the atmosphere and compensate for system induced optical aberrations.
