Title: Method for measuring surface by means of phase modulation interference
Inventor: HOSOE HIDE
IPC: G01B11/24
Filed: 1990-06-04
Abstract: PURPOSE:To reduce an error by calculating strength of an interference flux with a phase shift amount based on a change in distance as a function of a phase shift of an interference flux on optical axes of a Fizeau's reference surface from a surface to be inspected and an angle made by an optical axis of an incident reflected flux and the surface to be inspected. CONSTITUTION:With a distance on optical axes of a Fizeau's reference surface from a surface to be inspected varied, strength of an interference flux corre sponding to an (x, y) position in a rectangular coordinate with said optical axis of the surface to be inspected as the center is obtained by an equation. In the equation, Ia = (Imax + Imin)/2, gamma = (Imax - Imin)/(Imax + Imin), phi: initial phase, theta0: phase shift amount of the interference flux based on a change in a distance between optical axes of the Fizeau's reference surface and the surface to be inspected, psi : angle made by an optical axis of an incident reflected flux and the surface to be inspected. With this method, an error due to an influence of an angle psi can be prevented from being added to an initial phase of a position distant from the optical axis of the surface to be inspected.
