ABSTRACT:
An optical delay apparatus that regularly alternately outputs beams having mutually different delays on one optical axis and that can variably set a delay amount of at least one beam. A motor 112 rotation-drives a rotating plate 111 in which reflective portions and transmissive portions are formed regularly alternately in the circumferential direction. When an incident beam I0 is incident to a reflective portion of the rotating plate 111, it is reflected to generate a beam I1. When the incident beam I0 is incident to a transmissive portion of the rotating plate 111, a beam I2 transmitted is reflected by a reflector 120 to become a beam I3, and the beam I3 is again transmitted by the transmissive portion of the rotating plate 111. This beam I3 has a delay different from that of the beam I1, and the beam I3 and the beam I1 advance regularly alternately in the same direction and on the same optical axis. Further, the reflector 120 is arranged as movable by a moving stage 130, and the delay amount of the beam I3 changes with movement of the reflector.
