本文提出了一种用于矩形金属网的激光检测方法。可对运动中的金属网进行在线测量。它采用光学付里叶变换方法,利用CCD作为光电探测器,系统中应用了DMA高速数据采集系统和ΔPPLEⅡ微型机系统。与传统测量方法比较,它不但测量速度快,测量精度高,而且劳动 This paper presents a laser detection method for rectangular metal mesh. On-line measurement of moving wire mesh. It uses optical Fourier transform method, the use of CCD as a photodetector, the system uses DMA high-speed data acquisition system and ΔPPLE Ⅱ microcomputer system. Compared with the traditional measurement methods, it not only measurement speed, high accuracy, but also labor
