Abstract

PURPOSE:To make it possible to increase measuring points keeping the interval of interference fringe wide by analysing patterns of the interference fringe under a condition in which the measuring points are finely moved by displacement driving of the wedge shaped correction plate, so that the space resolutoon of measurement can be raised.
