DEVICE FOR ULTRASONIC IMAGING OF OBJECTS IN LIQUID MEDIA (EMBODIMENTS) Russian patent published in 2018 - IPC H04R17/00 G01N29/24 

FIELD: electricity.

SUBSTANCE: group of inventions relates to ultrasonic imaging of objects. Device for ultrasonic imaging of objects in liquid media comprises a generator and information processing unit, body, laser, first and second biconvex optical lens, translucent optical mirror, reflecting optical mirror, receiving matrix, flat-convex optical lens, disk with first through holes, in which a waveguide with input and output ends is placed, acoustic lens, acoustic radiator. Generator is electrically connected to the acoustic radiator and to the information processing unit, which is connected to the receiving matrix. Acoustic radiator is installed with the possibility of radiating signals into the external medium. Disk is installed with the possibility of receiving acoustic signals emitted by the acoustic radiator and reflected by the external medium on the input ends of waveguides through the acoustic lens. Flat-convex optical lens is installed in such a way that a sealed space arises inside the body. Waveguides are installed in the first holes in the disk. Disk is installed in the body, observing the gap between the second end of the disk and the flat side of the flat-convex optical lens. Disk is sealed to the body. Information processing unit is connected to the display by wires. Second cable is connected to the generator.

EFFECT: technical result is the ability to operate on reflecting acoustic signals and the ability of the sound machine to operate in liquid, including aggressive and dangerous media, in wide range of temperatures, with temperatures ranging from several degrees Celsius to five hundred degrees Celsius.
