Abstract

The rapid development of endoscopic photoacoustic imaging technology with the combination of endoscopic imaging and photoacoustic imaging has a great demand in clinical practice. Because the volume of the internal snooping head in the current study is limited by the volume of the ultrasonic transducer, the ultrasonic transducer with high sensitivity and small volume needs to be further explored and studied. We use a two-photon 3D lithography machine to process the well designed Fabry Perot(FP) cavity on the end of the double-clad fiber as the sensor probe, the two road light coupling into the double cladding fiber respectively, in which fiber core transmission of light as the excitation light all the way, in the first a pack of transmission between the layers of the reference light all the way, the use of the "spontaneous since" mode for nondestructive ultrasonic testing. Based on the design of F-P microcavity as a detection unit, a new all-optical detection system for endoscopic photoacoustic imaging is realized. It has great potential in clinical application research.
