摘要

摘要: 针对现有小功率半导体激光指向器的作用距离检测方法存在稳定性差、效率低的缺点, 提出了一种基于CCD测量技术的激光指向器作用距离检测方法。该方法采用CCD传感器及图像处理技术，对基于人眼为接收器的激光指向器作用距离公式进行了理论推导及建模，建立了CCD传感器接收光功率和输出灰度之间的函数关系，并运用最小二乘法求解出关系式中的相关系数，通过相关系数求解出作用距离，实现了小功率激光指向器作用距离的定量检测。实验证明了该方法的可行性。

Abstract: In view of the problem of poor stability, low efficiency existed in distance detection method of low power semiconductor laser pointer, a measurement method of detection distance of laser pointer based on CCD detection technology was put forward. The detection distance equation of laser pointer with human eye as the receiver was deduced and modeling by using the CCD sensor and image processing technology. The function mathematical model between the two parameters of optical power and gray scale was also established. The least square method was used to solve correlation coefficient of the equation，the detection distance can be solved by correlation coefficient. The method realizes quantitative detection of detection distance of low power semiconductor laser pointer. The feasibility of the method is verified by experiment.
