Abstract

PURPOSE: The need for having uneveness on the surface of a moving object to be measured is eliminated by using coherent light, accuracy is increased by increasing the number of gratings and in addition the formation of a filter and the measurement of signals are performed within the same optical system, whereby measurement is made with a simple measuring system.
