Abstract:
1. An optical connector used in an optical tomographic imaging system for acquiring an optical tomographic image of an object under measurement, the optical connector comprising: a holder unit; a first optical fiber fixedly supported by the holder unit and having on one end thereof an end face inclined a given angle with respect to a plane perpendicular to its optical axis; a first collimating lens disposed at a given distance from the inclined end face of the first optical fiber; a mounting unit supported with respect to the holder unit; a second optical fiber fixedly attached to the mounting unit, disposed opposite the first collimating lens, and having an end face inclined a given angle with respect to a plane perpendicular to its optical axis; and a second collimating lens fixedly attached to the mounting unit and disposed between the first collimating lens and the second optical fiber with a given distance from the inclined end face of the second optical fiber, wherein an optical transmission system comprising the first optical fiber and the first collimating lens is disposed symmetric to an optical transmission system comprising the second optical fiber and the second collimating lens with respect to a plane perpendicular to an optical axis, wherein the first optical fiber and the second optical fiber are supported by respective ferrules and the ferrules have inclined end faces forming same planes as the inclined end faces of the first optical fiber and the second optical fiber, respectively, and wherein the mounting unit fixedly supporting the second optical fiber and the second collimating lens is detachable from the holder unit fixedly supporting the first optical fiber and the first collimating lens.
