中文摘要：

为了研究线性相位反演（LPR）技术在自适应光学系统中的应用,在实验室搭建了一套基于该技术的自适应光学闭环实验系统,利用19单元变形镜对动态像差进行了实时闭环实验。实验对由变形镜产生的系统像差定标,得到远场定标图像,利用远场实测图像和定标图像之间的光强分布变化量直接复原出变形镜驱动器电压,控制变形镜校正像差。实验数据表明,基于线性相位反演技术的自适应光学系统可以对一定大小的动态像差进行实时闭环校正,并有较好的校正效果,论证了这种系统的可行性。这种系统硬件结构简单,算法运算量很少,速度很快。

In order to investigate the application of linear phase retrieval sensor in the adaptive optics system,an experiment adaptive optics system was established based on the linear phase retrieval method.The close-loop compensation ability to the dynamic aberrations was investigated and validated by using a 19- element deformable mirror.During the experiment,it was needed to calibrate the system aberration produced by the deformable mirror first and keep its image.And then the voltage of drivers can be retrieved by utilizing the different images between the actual image and calibrated image.Finally,the unknown aberration can be corrected by controlling the deformable mirror.The results indicated that the system can correct certain size aberrations,and it had a fine compensation effect.The adaptive optics system based on the linear phase retrieval method is excellent with simple structure,low calculation cost and high speed.
