Abstract

An apparatus for reflecting a light and changing the length of an optical path from a beam splitter to a light reflecting member, and back to the beam splitter, on a cycle at a high speed, includes a beam splitter and at least one light reflecting member that reflects one of the emerged lights from the beam splitter and reenters the light in the beam splitter, the light reflecting member being supported so as to perform a circular locus motion with the orientation of the light reflecting member being constant. The circular locus motion includes a motion in which the light reflecting member is moved in a distance direction with respect to the beam splitter. The light reflecting member is provided with a turning effect, which is converted into a circular locus motion to make the light reflecting member perform the circular locus motion.
