CCD传感器的系统误差和随机误差会引起激光光斑宽度的测量误差。以高斯光斑为例，用计算机仿真的方法分别分析了测量窗口大小、非理想积分采样、量化级数和读出噪声对高斯光斑宽度测量精度的影响，以及实验室8位CCD传感器的这四种误差源对高斯光斑宽度测量精度的综合影响。给出了最优测量窗口大小。对仿真结果进行了分析和讨论。
The system errors and random errors of a CCD sensor cause measurement errors of a laser spot width. Taking the Gaussian spot as example, the computer simulation method is used to analyze the influences of the measurement window size, the non-ideal integral sampling, the number of quantization lever and the read-out noise on the measurement precision of Gaussian spot width respectively, and the synthesized influences of these four kinds of error sources of the laboratory 8-bit CCD sensor on the measurement precision of Gaussian spot width. An optimal measurement window size is given. Simulation results are analyzed and discussed.
