OPTICAL POLYGON CALIBRATION USING ONLY ONE AUTOCOLLIMATOR

Rigoberto Nava-Sandoval, Rufino Díaz-Uribe

Abstract

In this paper we present a new measuring method to obtain the angular variations of the faces of an optical polygon using only one autocollimator. The method requires additionally an external beam splitter to divide the light from autocollimator and a flat mirror for second autocollimator emulation. The method can be used for polygons of any number of faces. In this case we present calibration results of a twelve faces polygon.
