Abstract
An optical coherence tomography (OCT) apparatus according to an embodiment is configured to split light from a light source into measurement light and reference light, project the measurement light on an object, and detect interference light generated from the reference light and the measurement light returning from the object. The OCT apparatus includes a dispersion unit and an information generation unit. The dispersion unit is configured to relatively change a dispersion characteristic of a measurement optical path which is an optical path of the measurement light and a dispersion characteristic of a reference optical path which is an optical path of the reference light, according to an operation mode corresponding to a depth range. The information generation unit is configured to generate information on the object according to the operation mode, based on a detection result of the interference light.
