Abstract

PURPOSE:To enable the improvement of a measurement precision, by a method wherein two edges, consisting of slits, are independently moved to find a change in mesurements obtained when only the one edge moves. CONSTITUTION:A light, passing through an incident alit 17, passes through a lens 18, a prism 19, and a lens 20 to image-form on an intermediate surface. The intermediate slit consists of edges 21 and 22 which move independently. A light, passing throygh the intermediate slit, is fetched, through a lens 25, a prism 26, a lens 27, and an injection slit 28 to be measured. The measurement is performed such that the two edges 21 and 22 are alternately moved to find a difference in an output flux emanated before and after the one eddge moves. Through the repeat of said operations, the measurement can be doen over the full length range. Even in case the parallel of the two edtes is poor, no leakage nor overlap occurs by all means. Resolution of a wavelength is determined according to the moving distance of the edge, and thereby resolution of the measurement can be easily improved.
