ACOUSTOOPTIC IMAGING DEVICE

摘要

This acoustooptic imaging device comprises: an ultrasonic wave transmitter (14) for transmitting an ultrasonic wave to be radiated into a subject; an acoustic lens (3) for converging a reflected ultrasonic wave from the subject; an acoustooptic cell (2) that contains an acoustooptic propagation medium part (24) through which the reflected ultrasonic wave propagates, the reflected ultrasonic wave having a sound velocity that is lower than the subject and being converged by the acoustic lens; a light source (13) for emitting converged light to radiate the ultrasonic wave propagated through the acoustooptic propagation medium part (24) in a direction that is not parallel to the travelling direction of the ultrasonic wave; and an imaging optical system (14) for detecting a Bragg diffracted light of the converged light that is generated at the acoustooptic propagation medium part (24) and converting the light into an electric signal.
