Ultrasonic Lateral Displacement Sensor for Health Monitoring in Seismically Isolated Buildings

Ultrasonic Lateral Displacement Sensor for Health Monitoring in Seismically Isolated Buildings

An ultrasonic lateral displacement sensor utilizing air-coupled ultrasound transducers is proposed. The normally-distributed far field of an ultrasound transducer in a lateral direction is taken advantage of for measuring lateral displacement. The measurement system is composed of several air-couple...
