Analysis and compensation of Repeatability for Ultra-precision Stage
초정밀 스테이지의 반복정밀도 분석 및 보정
Abstract
The refractive index of the laser interferometer is compensated using the simultaneously measured variations of room temperature and humidity in the method. In order to investigate the limit of compensation, the stationary test against two fixed reflectors mounted on the zerodur plate is performed firstly. From the experiment, it is confirmed that the measuring error of the laser interferometer can be improved from 0.12
