PROBLEM TO BE SOLVED: To provide an optical interference cross-section endoscope apparatus able to increase the resolution of a tomographic image while maintaining the frame rate required for observation.SOLUTION: The optical interference cross-section endoscope apparatus including an endoscope, an interference light detecting part, and a tomographic image generating part, comprises: an optical probe configured to deflect measurement light at its leading end and emit the light so as to carry out rotation scanning, and guide the reflected light of the measurement light to an interference light detecting part from the leading end a transparent member configured to transmit the measurement light to the leading end a channel having a reflecting member for reflecting the measurement light, and configured to guide the optical probe along an insertion part so that the leading end of the optical probe faces the transparent member and reflecting member a scanning position detecting section configured to detect the intensity of the reflected light of the measurement light, thereby detecting which one of the transparent member and reflecting member the measurement light is scanning and scanning speed control means for controlling scanning speed of the measurement light emitted from the optical probe based on the detection result of the scanning position detecting part.COPYRIGHT: (C)2012,JPO&INPIT【課題】観察に必要なフレームレートを維持しつつ、断層像の解像度を上げることが可能な光干渉断層内視鏡装置を提供する。【解決手段】内視鏡と、干渉光検出部と、断層像生成部とを備えた光干渉断層内視鏡装置が、測定光を先端部で偏向して回転走査するように出射すると共に測定光の反射光を該先端部から干渉光検出部に導光する光プローブと、先端部に測定光を透過させる透明部材と、測定光を反射させる反射部材とを有し、光プローブの先端部が透明部材及び反射部材に対向するように光プローブを挿入部に沿って案内するチャンネルと、測定光の反射光の強度を検出することにより、測定光が透明部材又は反射部材のいずれを走査しているかを検出する走査位置検出部と、走査位置検出部の検出結果に基づいて光プローブから出射される測定光の走査速度を制御する走査速度制御手段とを備える。【選択図】 図1
