Title

Optical Beamforming For Ultrasonic Phased Arrays

Abstract

Low-cost, lightweight, and compact optical beamforming techniques for ultrasonic phased arrays are described. The use of a pair of tiny stamp-size low cost nematic liquid crystal 2D optical array devices for the transducer control sites allows compact, low control power beamforming for large 2D transducer arrays. The control of numerous elements in a 2D format leads to higher resolution ultrasonic detection that can be useful in imaging application such as tumor detection in the medical field and tiny crack detection in machine parts inspection. Compared to an all-electronic controller, the proposed optical method for ultrasonic arrays can be beneficial in cases where cost, power, tunability, remote control, and resolution are considered.
