镜片全自动测量系统的研究

为了提高镜片焦度测量的精度和效率,针对镜片测量时因手动调节而存在镜片偏心等问题,提出了一种结合哈特曼检测法、机器视觉技术以及步进电机控制系统来测量镜片的技术方案。基于此方案设计并制作了一种镜片全自动测量系统。系统实现了对哈特曼光阑下多光斑实时大小和位置的分析,利用搭建的机械模块自动校准镜片位置并测量镜片。用-15m^-1~+15m^-1的球面镜片进行重复性测量,实验结果表明:该系统实现了镜片的全自动测量,检测结果符合国家检定规程的要求,与手动测量结果相比测量误差减少了0.02m^-1,提高了测量精度。

Research on Lens Automatic Detection System

Aiming at the problems of lens eccentricity due to manual adjustment during lens detection, a technical solution for measuring the lens by combining Hartmann detection method, machine vision technology and stepper motor control system is proposed. Based on this scheme, an automatic lens detection system is designed and manufactured. By analyzing the real-time size and position of multiple light spots, the host computer communicates with the microcontroller to control the movement of the mechanical module, thereby automatically calibrating the lens position and measuring the lens. -15m^-1~+15m^-1 spherical lens is used for repeatable measurement. The experimental results show that the system achieves full-automatic lens measurement, and the test results meet the requirements of national metrological standards. Measurement error is less 0.02m^-1 than manual measurement results, the accuracy is improvemented.
