Abstract:
1. An optical coherence tomographic imaging apparatus in which a beam from a light source is split into a measuring beam and a reference beam to guide the measuring beam to an object and to guide the reference beam to a reference mirror; and a tomographic image of the object is acquired based on a return beam of the measuring beam which is reflected or scattered by the object and the reference beam reflected on the reference mirror, the optical coherence tomographic imaging apparatus comprising: an illumination condition varying portion for varying an illumination condition of the measuring beam for the object between a first illumination condition in which a center part of the measuring beam is not blocked and a second illumination condition in which the center part of the measuring beam is blocked; and an image forming portion for weighting a first tomographic image acquired in the first illumination condition in which the center part of the measuring beam is not blocked and a second tomographic image acquired in the second illumination condition in which the center part of the measuring beam is blocked and composing the weighted first tomographic image and the weighted second tomographic image to thereby form a third tomographic image.
