Air sac type white light-radiant light multimoding endoscopic imaging system

The invention discloses an air sac type white light-radiant light multimoding endoscopic imaging system. The system comprises a first endoscopic mirror; a light source that is connected with one end of the first endoscopic mirror; a first imaging unit that is connected with the other end of the first endoscopic mirror; a second endoscopic mirror; an air sac which is connected with one end of the second endoscopic mirror, wherein the outer wall of the air sac is coated with fluorescent substances; a second imaging unit which is connected with the other end of the second endoscopic mirror. According to the air sac type white light-radiant light multimoding endoscopic imaging system, by the use of the air sac, radiant materials can be firmly attached to target on the wall of digestive tract innovatively, the effect of distance on resolution is eliminated, the resolution meets the criteria of clinical application, and the use of radiant light imaging method can greatly enhance the imaging sensitivity and singal-to-noise ratio; the system has the advantages that the prospecting depth is large and no additional injection of imaging agent is needed.
