Abstract:
1. An optical tomographic imaging apparatus comprising: an optical path length adjusting device which adjusts an optical path length of a reference light beam split from a source light beam outputted from a light source section; an optical probe including an optical fiber to which is entered a measurement light beam split from the source light beam, a lens that deflects and collects the measurement light beam outputted from the optical fiber, and a probe outer casing inside which the optical fiber and the lens are disposed and which is provided with a transmitting surface capable of transmitting the measurement light beam; and an interference light detecting device which detects an interference light beam from a multiplexed light beam produced by multiplexing the reference light beam whose optical path length has been adjusted by the optical path length adjusting device with a returning light beam from the optical probe, wherein an irregular corrugated structure is formed on the transmitting surface so that a part of a reflected light beam of the measurement light beam reflected off of the transmitting surface becomes scattered light beams.
