Abstract
A mirror unit consists of a half mirror and a mirror unit. The half mirror generates a transmitted light and a reflected light. A pair of the mirror units is arranged on one side and the other side of the half mirror so that the transmitted light and the reflected light split by the half mirror are deflected and are combined again at a common place on the half mirror. The mirror unit also has plural mirrors and is arranged to make the optical length variable by shifting the mirror unit toward one direction with a moving mechanism.
