An optical coherence tomography apparatus (1) includes: a light source (102); an optical coherence tomography optical system (100) including: a first light splitter (104) which splits light emitted from the light source into a measurement light and a reference light, a second light splitter (302) which splits the measurement light into a first beam and a second beam independent from each other, an optical delay path (300) provided in an optical path of the measurement light to generate an optical path length difference between the first beam and the second beam, a scan optical system (108) which scans the respective beams on an object to be examined in a transverse direction, a reference optical system (110), and a detector (120) which receives a spectrum of composite light in which a reflected light of the first beam from the object to be examined, a reflected light of the second beam from the object to be examined, and the reference light from the reference optical system are combined; and an arithmetic controller (70) which processes an interference signal output from the detector to obtain a first tomographic image formed by the first beam and a second tomographic image formed by the second beam. |
