ULTRASOUND CONTROL SYSTEM Russian patent published in 2014 - IPC G01N29/24 

FIELD: instrument making.

SUBSTANCE: this invention can be used for ultrasound control. Ultrasound control system comprises multiple receiver and transmitter units. Every said transmitter unit can generate ultrasound oscillation at object surface and/or in said object. Every said receiver unit can perform optical measurements of object surface oscillations. Receiver unit can receive the light falling thereat from measurement zone. One measurement zone corresponds to one receiver unit for it to receive the light falling thereat from measurement zone. Note that every transmitter unit creates a spark gap. The latter generates ultrasound oscillations on object surface or there inside. Shield is arranged between spark gap and measurement zone. Receiver unit incorporates illumination laser to illuminate to surface in measurement zone and LED system to radiate laser light in its first position into first measurement zone and into second measurement zone in its second position. LED system splits laser light to radiate in one or another measurement zone.

EFFECT: higher SNR at low pulse rate, higher efficiency of conversion of electric power to ultrasound power.
