OCT OPTICAL PROBE AND OPTICAL TOMOGRAPHY IMAGING APPARATUS

摘要

Safe and inexpensive visual confirmation of the scanning position of an OCT optical probe, which is inserted into a forceps channel of an endoscope, is provided. The OCT optical probe to be inserted into a forceps channel of an endoscope that applies illumination light to a site to be observed in a body cavity and images reflected light from the site to be observed, includes: a substantially cylindrical and long sheath to be inserted into the body cavity; a distal end optical system disposed in the sheath and being rotatable about the longitudinal axis of the sheath; and a ferrule integrally fixed to the distal end optical system, wherein the ferrule includes a reflecting section adapted to reflect a part of the illumination light toward the endoscope.
