摘要
A wavefront sensing and correction correction is proposed that would allow the field of view (FOV) of an adaptive optics spstem to be increased in size by a factor of several tens. This concept is based on the idea of placing multiple deformable mirrors (DMs) at locations that are conjugate to corresponding. layers of atmospheric turbulence. In order to control properly each DM, a tomographic method for determining the phase distortion contributed by each atmospheric layer has been developed and used in dealing with the circumstance of two layers.
讨论了可使自适应光学系统的视场角大幅度增加的层析原理．首次提出分区计算子孔径所引起的相位畸变的方案，从而解决了以往文献中独立方程的个数少于未知数个数的困难．对两个变形镜的情况作了进一步的分析．
