Abstract
An optical coherence tomography apparatus which acquires a tomogram of a target object based on a light intensity detected for each wavelength by combining return light of measurement light from the target object with reference light corresponding to the measurement light, the apparatus comprising: a normalization unit adapted to normalize the light intensity detected for the each wavelength based on a transfer function corresponding to the wavelength resolution; and an image formation unit adapted to form a tomogram of the target object from the light intensities normalized by the normalization unit.
