Abstract
An object of the present invention is to widen a range in which line of sight change is possible, particularly in a pan direction. According to the present invention it is possible to acquire high line of sight changing speed. A pan mirror is capable of rotation in forward and reverse directions about a third rotational axis. Also, the third rotational axis extends in a direction that is substantially parallel to a line of sight direction directed from a tilt direction control section to the pan mirror. An angle α formed by the pan mirror and the third rotational axis is set in a range 0°<α<90°. The tilt direction control section can scan line of sight direction with respect to a virtual plane formed by a rotation locus of the pan mirror. The tilt direction control section can also control tilt angle of the line of sight direction from the pan mirror to a physical object. The pan mirror can control pan angle of the line of sight direction from the pan mirror to the physical object by being rotated about the third rotational axis.
