PROBLEM TO BE SOLVED: To enable improvement in loss of light amount of an OCT optical system.SOLUTION: An optical coherence tomography device comprises: a first optical divider that divides light emitted from an OCT light source into a first measurement optical path and reference optical path; a light guide optical system that is for guiding measurement light from the first measurement optical path to a sample via a second optical divider, and includes the second optical divider dividing reflection light from the sample by the measurement light into the first measurement optical path and a second measurement optical path; a detection optical system that is for detecting first interference serving as interference of the reflection light via the first measurement optical path with the reference light via the reference optical path, and second interference serving as interference of the reflection light via the second measurement optical path with the reference light via the reference optical path; a computation processing instrument that processes an output signal to be output from the detection optical system to obtain OCT data on the sample.SELECTED DRAWING: Figure 1 |
