可变形反射镜(Deformable_Mirror)是自适应光学系统中的核心部件之一,它担负着校正由内、外因素引人的波前误差的任务,并补偿由光路中各种因素引起的成像质量降低的问题,即校正器。按照驱动方式的不同,可变形反射镜分为:(1)压电式;(2)电磁式;(3)电致伸缩式;(4)液压式;

荷兰OKO公司的MEMS薄膜变形镜采用MEMS技术制造,为静电驱动的连续镜面变形镜,具有体积小、成本低、响应快以及集成度高等传统变形镜不具备的特点。可应用于包括激光光束控制、腔内激光控制、实时大气校正、全息、光通信等领域。镜面以铝膜为标准反射膜,用户也可以定制其他金属膜或多层介质反射膜。MEMS变形镜的全幅度的响应快于150μs,由于受限于电子系统,响应时间一般在1ms,可提供动态波前畸变校正。 

 

MEMS薄膜变形镜主要特点:
 
零滞后,可以工作在1kHz的频率范围; 校正范围大,变形量可达25μm; 成本低;小而轻;功率消耗小;高镜面质量
