PROCESS OF REGISTRATION OF ULTRASONIC PULSES IN SOLID BODY

摘要

A process of registration of ultrasonic pulses in solid body comprises stages of excitation of acoustic pulses in the sample by means of transducer, amplification of the image of (reflected) signals and indication. Pulse filling at the stage of generation is performed with high-frequency vibrations, deviation of those takes place by random law within set limits close to resonance frequency of the transducer with following digital averaging of the results of observations.
