方差分析在激光点光源质量评价中的应用

为了更好地评价激光点光源的发光质量,本文引入方差分析来研究激光点光源的系统误差以及随机误差。首先,本文从理论上推导了理想激光点光源的统计学模型,分析了理想点光源的基本统计学性质;之后,将方差分析引入了点光源质量评价之中,提出了一种检验激光点光源发光均匀性的检测方法并利用本文所提出的方法,对于某激光点光源的发光质量进行评价,得出了在0.99的置信概率下,其系统误差分布均匀的结论,验证了本文理论的正确性以及方法的可行性。最后以三十米望远镜为背景考虑了本文方法在下一代大口径光电系统误差分析中的应用。本文的工作对于点光源的发光质量评价有着一定指导意义;同时,对于光电系统的误差分析也有很好的帮助作用。

Variance analysis in the application of the laser point source quality evaluation

In order to evaluate the laser point source,the variance analysis is introduced to study its stochastic error and system error. Firstly,the theory statistics modal of ideal point source is built to specify the basic statistics property. Then,variance analysis is introduced to the evaluation of laser point source,and a method to measure the uniformity of laser point source is proposed. The luminous mass of certain point source was evaluated with the method;error distribution of the system is uniform at the confidence probability of 0.99,which verifies the correctness of this theory and the feasibility of this method. Lastly,taking the TMT for example,this method is considered in the application of optoelectronic system variance analysis of the next generation large aperture telescope. This method has a certain guiding significance for the laser point source evaluation,and it is helpful for error analysis of optoelectronic system.
