Research Abstract

We have developed a new measurement technique for nm-level change of an optical-path-deference(OPD) using laser. This technique can measure OPD of a vertical-scan interference microscope real time and high speed. With the technique we can trigger LED flashings and interferogram exposures right after predefined phase changes even under vertical vibrations. Analyzing the measured 3D-shape obtained with the technique results in that affects of vibration during the exposure should be corrected for higher precision shape measurement. Then we have developed another technique which can extract interference phase just on the exposure-start moment from vibration-affected interferogram intensities and history of OPD changes during the exposure. Validity of the developed technique is proved by experiments using the vertical-scan interference microscope with intentionally generated pulse-like vibration.
