Abstract
The Nondestructive Evaluation Group of the Defence Research Establishment Pacific (DREP) has transformed a commercial ultrasonic digitizer into an accurate three-dimensional position measurement system to guide a surface scanning robot. Four ultrasonic receivers were configured to produce the three dimensional position of an ultrasonic transmitter. By using a second transmitter to measure the speed of sound, the accuracy of the commercial digitizer was improved by a factor of five.
