OCT is playing an important role in interventional operations and some other therapies recent years. In many interventional operations the temperature of the tissue is also one of the main factors that will influence the operation result. Therefore monitoring the temperature of the operational tissue real time is critical for the operation and therapy. In this paper an endoscopic OCT probe for interventional operation with real time temperature monitoring function is presented. It consists of a micro OCT probe and a fluorescence thermometer. These two parts are installed in a base with a transparent shell of 3.0mm diameter and share one light source. Principles and structures of each part and the whole system are stated in detail. The experimental results indicate that the interventional operations OCT system can be used for rotated scanning imaging to obtain more tissue information and at the same time the temperature of the operational tissue can be monitored precisely.
