摘要
空间光调制器是自适应光学系统中用来实时校正波前畸变的关键器件,其发展水平能够反映整个自适应光学系统的水平。基于微电子机械系统(MEMS)技术的空间光调制器具有体积小、能耗低、驱动器单元密度高以及与集成电路工艺兼容性好等优点,而成为空间光调制器领域研究的热点。详细介绍了MEMS空间光调制器的研究现状和存在的主要问题,并分析了MEMS空间光调制器的未来发展趋势。
Spatial light modulator is a key component used to correct the wavefront aberration in an adaptive optics system,whose development level can reflect that of the whole adaptive optics system.Micro-electro-mechanical systems(MEMS)based spatial light modulators have advantages of small volume,low power consume,high actuator density and good compatibility with integrated circuit process,and therefore have been the focus of study.The development states,main problems and development tendency of the MEMS based spatial light modulators are presented in this paper.
