Abstract

PURPOSE:To improve the accuracy of directivity to an object by controlling the drive of a gimbal mirror so that an error of the gimbal mirror from a regulated angle due to a difference between the projecting position of measuring light at an angle difference detecting part and its incident position. CONSTITUTION:The object 9 is set up in front of a base 1, and when the gimbal mirror 6 is driven so that measuring light 20 projected from the angle error detecting part 19 vertically to the base is returned to the original position, the normal of the mirror 6 is turned to 45 deg. direction from the object 9, so that incident light 10 can be converged into the center of an image pickup device 11. Since the object is rotated from the base 1 by an angle theta, the movement of the gimbal mirror 6 for returning the measuring light 20 projected from the detecting part 19 to the original position corresponds to turning the normal of the mirror 6 from the object 9 in the 45 deg.+theta/2 direction, so that the error of the mirror 6 from the regulated angle can be removed and the incident light 10 can be converged into the center of the device 11.
