本文阐述了一种新型的检测技术,其基本思想是利用光学手段—光学傅里叶变换提取工件的误差信息,经光电转换将误差信号变成电信号,并送入微计算机进行数据处理,进而实现自动传送工件,自动测量和分类。这种方法可将误差信息放大千百倍,大大提高测量的灵敏度和精度(可达μm级)。如能增加自动校准反馈装置,实现测量过程的全自动化,那对提高国民经济效益,减轻工人的劳动强度将会起着巨大的作用。
This article describes a new detection technology, the basic idea is to use optical means - optical Fourier transform to extract the error information of the workpiece, the error signal by photoelectric conversion into electrical signals, and sent to the micro-computer for data processing, and then to achieve Automatic transfer of workpieces, automatic measurement and classification. This method can amplify the error information thousands of times, greatly improving the measurement sensitivity and accuracy (up to the μm level). If the automatic calibration feedback device can be added to realize the full automation of the measurement process, it will play a huge role in improving the national economic benefits and alleviating the labor intensity of the workers.
