Abstract

The optical tomographic imaging system includes a main body for acquiring an optical tomographic image, an optical probe having a rotary optical fiber for guiding the measuring and returning light, a measuring unit, and a sheath rotatably holding the rotary optical fiber and the measuring unit, a rotary drive unit for rotatably coupling the rotary optical fiber to a stationary optical fiber connected with the main body, an extra length handling mechanism for winding the optical probe into a loop having at least a minimum diameter and an attaching unit removably attaching the optical probe. The extra length handling mechanism winds an extra length of the optical probe by a length depending upon a length up to the location to be examined. The system eliminates the need to change the optical probe depending upon the location to be examined and the need to adjust the optical path length of reference light.
