Title:
ACOUSTOOPTIC IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/183302
Kind Code:
A1
Abstract:
This acoustooptic imaging device comprises: an acoustic wave source (1); an acoustic lens system (6') for converting a scattered wave (5) that is caused by a subject being irradiated with an acoustic wave (2) emitted from the acoustic wave source (1) into a prescribed converged state; an acoustooptic medium part (8) that is disposed such that the scattered wave which passes through the acoustic lens system (6') enters therein; a light source (19) for emitting a light beam in which a plurality of monochromatic lights with different traveling directions to each other are superimposed, the light beam entering the acoustooptic medium part at an angle that is non-vertical and non-parallel with respect to the sound axis of the acoustic lens system (6'); an imaging lens system (16) for converging diffracted light of a plurality of plane wave monochromatic lights generated at the acoustooptic medium part; and an image receiving part (17) for detecting the light that is converged by the imaging lens system (16) and outputting an electric signal. The acoustic lens system (6') contains at least two reflective mirrors.
