Experimental results from an adaptive optics system based on a dual frequency nematic device

High Closed Loop Correction Accuracy with a Liquid Crystal Wavefront Corrector

“…Some researchers have used them in adaptive optics systems and acquired significant results in laboratory. [7,8] Dayton et al [9] installed an adaptive optics system with a dual-frequency liquid crystal wavefront corrector (LC WFC) in a 3.67 m telescope to correct the distortions of turbulence and obtained the resolvable image of the International Space Station. For the correction accuracy of an adaptive optics system, the number of active elements is a decisive factor.…”
