Abstract：
 The present invention relates to a real-time imaged optical coherence endoscopic system. Said invention includes broad-band light source, optical fibre coupler, sample arm and reference arm, position detector and computer collecting and processing system, and said system structure is based on Michelson interferometer, the described reference arm adopts the scanning disk connected with motor, and said scanning disk is formed from central shaft and flabellum which is placed on the central shaft and whose at least one surface form is equidistant spiral surface. The sample arm adopts micro-type optical transmission and scanning device based on ultrasonic motor. Said invention is simple in structure and can provide scanning range greater than 3 mm.
