The invention belongs to the technical field of photoacoustic detection, and discloses a transceiving integrated all-optical ultrasonic
transducer device and a preparation method thereof. The device comprises a structured base (2), a suspension film (3), a double-clad
fiber (1) and an F-P cavity (4), wherein the F-P cavity is constructed by the cooperation of the structured base, the suspension film and the double-clad
fiber; the suspension film is a composite photoacoustic conversion film,
laser beam energy of an excitation light can absorbed and the
laser beam energy can be converted into ultrasonic
waves which is emitted outwards, and transmission of sound
waves are realized; and meanwhile, the ultrasonic echo can be received,
acoustic wave return signals are sensed by deformation, thecavity length of the F-P cavity and the returned detection optical signals are influenced, and the returned detection optical signals are detected, so that receiving of sound
waves can be realized. According to the invention, the structures of all components and the cooperation working mode of the components are improved, the whole process of
ultrasonic transmission and reception can be completedon one suspension film by utilizing the suspension film and the F-P cavity which is further constructed, the device is more compact in structure, the photoacoustic imaging operation is simpler, and the result is more accurate.
