OPTICAL PROBE FOR OPTICAL COHERENCE TOMOGRAPHY AND MANUFACTURING METHOD THEREFOR

摘要

To provide an optical probe for OCT and a method of manufacturing the optical probe that can reduce reflected light generated at a boundary portion between an optical fiber and a lensed fiber. An optical probe for OCT includes an optical fiber that transmits irradiation light and back-scattered light and a lensed fiber that is fusion spliced to an end face of the optical fiber, that emits irradiation light toward the inside of a living body while collimating the irradiation light, and that collects and guides back-scattered light to the end face of the optical fiber. A refractive index adjusting material is added to the lensed fiber, and the refractive index adjusting material is diffused in an end part of the optical fiber.

主权项

1. An optical probe for optical coherence tomography comprising:
an optical fiber that transmits irradiation light and back-scattered light; and a lensed fiber that is fusion spliced to one end of the optical fiber, that emits the irradiation light toward an object to be measured while collimating the irradiation light, and that collects and guides back-scattered light from the object to be measured to the one end of the optical fiber, wherein a material for adjusting a refractive index is added to the lensed fiber, and the material is diffused in an end part of the optical fiber including the one end.
