Front surface matched piezoelectric ultrasonic transducer array with wide field of view

摘要: An ultrasonic transducer array with high sensitivity, for use in water tanks and human subjects steered beam imagers to make wide angle sector scans, has narrow elements one or more quarter-wavelength impedance matching layers on the front surface of each element. The as well piezoelectric ceramic are completely cut thorugh guide acoustic energy incident at any ceramic. A continuous covering wear plate is attached a damping material can cover backs elements.
