PROBLEM TO BE SOLVED: To solve a problem wherein a disc is difficult to be compactified, precise balance regulation is required for high speed rotation and an optical system is complicated, although the disc arranged with a plurality of right-angled prisms with an equal interval is rotated at a high speed as a high-speed optical delay device in a reference light side, so as to quicken depth-directional scanning, in the prior art, a problem wherein a data is not acquired in an instantaneous time when not irradiated with a reference light in a prism rotation switching time, a problem wherein an amount of signals returning from a specimen is reduced because an irradiation light is due to a sector system to require correction by a lens or the like for bringing the irradiation light in parallel, in a system of acquiring quickly the data by arranging a light scanner in a sample side, and a problem wherein the light scanner comes into a probe because of structure thereof, to weaken vibration and impact. SOLUTION: An optical system is most simple and an amount of recursion signal light is great, and the continuous data is acquired, in a system of the present invention for reflecting a reference light by a high-speed light delay mechanism of reciprocating linearly a reference mirror at a high speed.
