OPTICAL COHERENCE TOMOGRAPHIC IMAGING APPARATUS AND CONTROL APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/121962
Kind Code:
A1
Abstract:
A tomographic imaging apparatus configured to acquire a tomographic image or a cross-sectional image of an object to be examined from signals of a plurality of interfering beams obtained by emitting a plurality of measuring beams to the object to be examined and causing return beams of the measuring beams to interfere with reference beams includes a sensor configured to detect the plurality of interfering beams to acquire signals of the plurality of interfering beams, an acquisition unit configured to acquire an optical characteristic in the tomographic imaging apparatus corresponding to each of the plurality of interfering beams, and a generation unit configured to generate a tomographic image or a cross-sectional image of the object to be examined based on the signals of the plurality of interfering beams and the optical characteristic.
