FIBER BUNDLE AND ENDOSCOPE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fiber bundle for branching light and an endoscope device with which the tomographic image by an OCT is obtainable. SOLUTION: The fiber bundle 16 which is a composite bundle 16a bundling optical fibers S and G on the front end side, is an OCT bundle 16b bundling only the optical fibers S and an image bundle 16c bundling only the optical fibers G is used. The optical fibers R of the same number are respectively optically coupled to an optical coupler 323 to the optical fibers S and an SLD 321 is disposed to face the terminal surface of the optical fibers S. In addition, a photodetecting part 322 is disposed to face the terminal surface of the optical fibers R. The OCT bundle 16b is used for image pickup of the tomographic image of the examinee by the OCT and the image bundle 16c is used for image pickup of the ordinary image or fluorescent image of the examinee.
