Abstract
An optical coherence tomograph includes: a light source configured to output light; a branching portion configured to separate the light from the light source into irradiation light and reference light; a reference optical system configured to transmit the reference light from the branching portion; an irradiation optical system configured to transmit the irradiation light from the branching portion so that an object is irradiated therewith, and transmit reflection light of the irradiation light reflected by the object; a coherence portion configured to generate coherent light by causing the reflection light from the irradiation optical system and the reference light from the reference optical system to be coherent; a coherent light output portion configured to output the coherent light; and a coupling element configured to function as the branching portion and the coherence portion.
