Combined Optically Addressable Spatial Light Modulator forAffordable Adaptive Optics

摘要

Combining high-end sensor, display and field programmable gate array technologies a new combined optically addressable spatial light modulator device is developed, and built. Parallel, programmable hardware provides an efficient way to process the measured wavefront data. Using these data and appropriate phase modulation of the built in LCOS display a complete adaptive optic system can be implemented. As it is built from commercially available, sophisticated components it provides an affordable solution, without real compromise between the achievable resolution, speed and overall performance. Primarily, we intend to apply this device in solar telescopes, where high speed, high resolution, correlation based wavefront sensing is required.
