Abstract

See full text

An optical coherence tomography device includes: an OCT optical system configured to obtain a OCT signal; a front observation optical system configured to obtain a front image of the test substance; and a controller is configured to: control the OCT optical system to obtain first temporally different OCT signals with respect to the test substance; control the front observation optical system to obtain a first front image of the test substance at the time the first OCT signals are obtained; control the front observation optical system to obtain a second front image of the test substance after that; determine whether or not the plurality of first OCT signals are good based on a positional deviation between the first and second front images; and obtain motion contrast data of the test substance when it is determined that the plurality of first OCT signals are good.
