METHOD FOR ULTRASONIC CONTROL OF OBJECTS

摘要

Method for ultrasonic control of objects includes emission of ultrasonic vibrations (UZK) and passing those through object of control (OK) and standard object, reception of UZK and determination of time of passage of UZK in object of control and standard object. Points of emission of UZK and points of reception of UZK are placed on parallel straight lines. Object of control and standard object are fixed at same time between points of emission and reception of UZK. As reference object one uses object that is made with possibility of change of its geometrical dimensions. Rate of propagation of UZK and OK is determined by formula.
