JUST ABOUT THE PHYSICAL BASICS OF ULTRASONIC TRANSDUCER PHASED ARRAY IN SIMPLE TERMS. Part 3
(pp. 4-15)

Abstract. Part 3. Features the work of normal probes with a rectangular phased array This is the third article in a series of publications on transducers array probe (TAP) in which a simple (almost no formulas) description of the physical basics of operation of such probes are given. It deals with the features of the emitted and recorded signals normal TAP with a rectangular (two-dimensional) array with different size sides. The article shows the influence of the shape of the array on the variation of the amplitude of a signal emitted by the TAP along the acoustic axis, the directivity characteristic, the amplitude of the bottom signal, etc. The material is available for understanding the operators of all skill levels.

Keywords: normal probe , rectangular phased array, focus distance, directivity characteristics, crystal, beam axis, bottom echo, DGS-diagram.
