ABSTRACT:
A link-mechanism base is prepared within a yoke portion, and a link member is prepared in connection with the base within left and right supports. The link member connects the upper part of the supports or the upper part of the yoke portion, and the link-mechanism base. The displacement and angle of rotation of the upper part of the yoke portion are measured by using these link-mechanism base and link member, thereby measuring a change in the pointing direction of a reflector.
