JUST ABOUT THE PHYSICAL BASICS OF ULTRASONIC TRANSDUCER PHASED ARRAY IN SIMPLE TERMS. PART 4
(pp. 20-31)

Abstract. Comparison of theoretical and experimental results of research of work of transducers with a phased array and some features and opportunities of their practical application at the ultrasonic control In the final article of a series of publications on phased array transducers (TAP), which gives a simple (almost without formulas) description of the physical basis of such transducers, some results of comparison of theoretical and experimental characteristics of TAP and describes some features and possibilities of their practical application in ultrasonic testing. It is shown that the theoretical models of normal and angle probes with linear phased array adequately describe the operation of the TAP. A number of examples of the use of TAP in practical testing, showing their features and real possibilities.

Keywords: normal probe, phased array, depth of focus, directivity characteristic, angle of probe, delay line, bottom echo, reflector.
