Claim:
1. An optical coherence tomography apparatus comprising: an OCT light source configured to emit a light; a first light splitter configured to split an optical path of light emitted from the OCT light source into a first measurement optical path by which measurement light is guided and a reference optical path by which a reference light is guided; a light guide optical system including a second light splitter through which the measurement light from the first measurement optical path is guided, the light guide optical system being configured to guide the measurement light to a test substance through the second light splitter, the second light splitter being configured to split light reflected from the test substance based on the measurement light, into the first measurement optical path and a second measurement optical path; a detection optical system configured to detect first interference between the reflected light having passed through the first measurement optical path and the reference light, and second interference between the reflected light having passed through the second measurement optical path and the reference light; and a calculation controller configured to process an output signal which is output from the detection optical system to obtain OCT data regarding the test substance.
