摘要：
Liquid crystal (LC) based spatial light modulators (SLM) offer a low cost alternative to the expensive deformable mirrors used in most adaptive optics systems. Real time correction of simulated atmospheric turbulence is demonstrated. The corrective element is a 10 by 10 pixel ferroelectric liquid crystal (FLC) SLM. An improvement in the Strehl ratio from 23% to 33% with a frame rate of 6Hz was demonstrated. A nematic liquid crystal (NLC) SLM was used to generate realistic atmospheric turbulence.
