Abstract
PURPOSE: To easily and accurately measure the angle of fall of the mirror surface of a beam deflecting mirror during its beam deflecting operation by measuring the focal point of the beam, when the angle of fall of the mirror surface is at a normal value, and the movement of the focal point resulting from the deflection of the mirror surface.
