To diminish the static phase aberrations of large aperture lasers and promote the concentration degree of focal spot, phase corrector plate is proposed.
为了减小大口径激光系统的波前畸变并提高焦斑能量集中度，对静态波前畸变采用了相位板补偿的方法。
Using active optics technique to control its reflecting corrector makes it a unique astronomical instrument in combining large aperture with wide field of view.
应用主动光学技术控制反射改正板，使它成为大口径兼大视场光学望远镜的世界之最。
A new lower-resolution subzonal wave-front corrector can be approximated by subdividing the wave-front corrector's aperture into multiple subzones, all actuators associated with each subzone being treated as a whole controlling element.
