Low-frequency transducers that contain piezoelectric and passive layers
Source abstract
Abstract
The problem of obtaining short echo-signal pulses using multilayer transducers that consist of alternating active and passive layers is considered. The time characteristics of a transducer for a frequency range of 50–500 kHz are analyzed. The main requirements that are imposed on the transducer, amplifier, and generator of the electronic unit are formulated. The parameters of the transducer that allows the duration of an echo pulse to be reduced to a value that is approximately 5–10 times smaller than the pulse duration, which results from the use of a single piezoelectric element, are determined.
