摘要:
An acousto-optic imaging device includes: an ultrasonic wave transmitter for transmitting a divergent ultrasonic wave into a subject an acoustic lens for converging a reflection ultrasonic wave derived from the ultrasonic wave from the subject an acousto-optic cell including an acousto-optic propagation medium section which has a smaller sound velocity than the subject and through which the reflection ultrasonic wave converged by the acoustic lens propagates a light source for emitting convergent light so as to irradiate the reflection ultrasonic wave propagating through the acousto-optic propagation medium section in a direction not parallel to a traveling direction of the reflection ultrasonic wave and an image formation optical system for detecting Bragg diffracted light of the convergent light which is produced in the acousto-optic propagation medium section and converting the detected Bragg diffracted light to an electric signal.
