Title: Method of measuring surface shape
Inventor: MOROKUMA HAJIME
IPC: G01B9/02
Filed: 1993-12-28
Abstract: PURPOSE:To realize a simple method, wherein the number of times of the measurements is small, capable of being advantageously utilized as a surface shape measurement method in the case of using an interferometer. CONSTITUTION:As an interferometer, for example, a shape-measurement interferometer 1 is utilized and a plane 3 to be measured and an auxiliary plane 4 are used. A shape distribution measured from an interference fringe obtained by skillfully combining the plane 3 and plane 4 is obtained on each arrangement condition. A shape of the plane to be measured is calculated from a shape distribution at a time when the plane 3 is disposed in an optical path 2 by an angle of theta1, a shape distribution at a time when the plane 3 is disposed in the optical path by an angle different from the angle of theta1 and, for example, a shape distribution at a time when the plane disposed by the angle of theta1 is moved in one of the directions of the plane at a prescribed distance. The shape of the plane to be measured is calculated from the shape distribution obtained by combining the shape-measurement interferometer 1, the plane 3 and plane 4 so that a surface shape is accurately measured. The shape distribution is apparent from three times of measurements, thereby reducing the number of times of measurements and simplifying the measurement.
