用激光干涉法动态测量圆钢直径

Dynamic Measuring of the Diameter of Cylindrical Steel Rod with the Method of Laser Interference

提出一种用激光干涉法快速、无接触、动态测量圆钢直径变化量的方法。采用该方法，并加上自动反馈装置后可进行生产过程的自动控制。

This paper puts forward a new method of rapidly.uncontactly, and dynamicly measuring the variation of diameter of cylindrical steel rod in production with the method of laser interference.Fhis method can be used for automatic control in production by adding an automatic feedback device.
