发明名称 Wavefront measuring method and projection exposure apparatus
摘要 A method of measuring a wavefront aberration of a predetermined optical system being serviceable for imaging a pattern. The method includes storing information related to a light intensity distribution on a pupil plane of the predetermined optical system in a reference state, and detecting a wavefront of the predetermined optical system in an arbitrary state, on the basis of the stored information.
