A Parametric Array for Use As an Ultrasonic Proximity Sensor in Air

Wednesday, November 2, 1988 1:00 p.m. Yang-Sub Lee Department of Mechanical Engineering The University of Texas at Austin Ultrasonic proximity sensors are used in robotics and other industrial processes to locate objects in air without direct physical contact. We investigate the possibility of using an ultrasonic proximity sensor employing a parametric array as an alternative…
