DEVICE FOR CONTACTLESS HIGH-PRECISION MEASUREMENT OF OBJECT PHYSICAL AND TECHNICAL PARAMETERS

摘要

FIELD: physics. ^ SUBSTANCE: device for contactless measurement of physical and technical parameters of object comprises body with inlet and outlet for running liquid and contains high-frequency ultrasonic radiator including buffer rod and piezoelectric plate fixed on it with electrodes for connection to external high-frequency generator. Device comprises acoustic lens installed in body and arranged with the possibility of displacement along its axis for focusing of sonic signal in object, acoustooptical shaper of optical image of sonic signals with two acoustooptical channels, measurer of acoustic lens displacement, computer. ^ EFFECT: expansion of functional resources. ^ 15 cl, 8 dwg
