| 摘 要： | 分析了哈特曼-夏克波前传感器采用模式法重构波前相位算法的数学模型，仿真实验了重构模式之间不正交对重构精度的影响，指出模式之问的不正交不影响算法的实现。在哈特曼一夏克传感器应用模式法进行波前测量和波前校正的过程中，模式之间的正交性并不是算法实现的必要条件，正交化处理算法对波前重构、波前校正精度的提高没有影响。

| Abstract: | The mathematic model of modal wavefront reconstruction using Hartmann Shack (H S) wavefront sensor is analysed. The effect of non orthogonalisty of the mode on the reconstrution precision is simulated, and it is indicated that the non orthogonality does not affect the use of modal algorithm. The conclusion is that the mode orthogonality is not a necessary condition in the course of wavefront measurement and correction using Hartmann Shack sensor, and the orthogonalizing algorithm cannot improve the measurement and correction precision in Hartmann Shack sensor and adaptive system. |
