Abstract

A high speed and high resolution dynamic range finding device for the measurement of large distances was developed. It was comprised of an ultrasonic transmitter and a receiver. The amplitude of a continuous ultrasonic wave was modulated by a low frequency acoustic signal. The range finding was achieved by detecting the phase difference between the transmitted and received ultrasonic signals. The design principle, hardware implementation, experimental results and performance analysis of the device are included. Experiments show that the accuracy of the device can be up to 1 mm within 1.5 m while its dynamic data update rate can be up to 40 kHz.
