优化设计的目的是用最少的通道数（探测器的像元数）探测最高阶的波前畸变。由此使探测器的探测精度高，系统简单，在极弱光探测条件下可探测光强低。由响应矩阵元的定义式可知，影响Ｚｅｒｎｉｋｅ模式系数传感器可探测和重构波前Ｚｅｒｎｉｋｅ多项式项数的主要因素是探测器的形状，即探测器的内部像元数和边缘像元数及它们的排列形状。如何根据需要重构的Ｚｅｒｎｉｋｅ多项式的项数来选择合适的探测器像元数及它们的排列，是本文优化设计的研究目的。
The purpose of the optimized design is to detect the highest order wavefront distortion with the fewest number of channels (detector pixels). As a result, the detection accuracy of the detector is high, the system is simple, and the light intensity detectable under a very weak light detection condition is low. According to the definition of the response matrix element, the main factors affecting the number of Zernike polynomials that can be detected and reconstructed by the Zernike mode coefficient sensor are the shape of the detector, that is, the number of internal and edge pixels of the detector and their Arrange the shape. How to select the appropriate detector pixel number and their arrangement according to the number of Zernike polynomials needed to be reconstructed is the research goal of this paper.
