METHOD AND SYSTEM FOR CORRECTING FOR TEMPERATURE VARIATIONS IN ULTRASONIC TESTING SYSTEMS

摘要

A method and system for correcting for temperature variation in ultrasonic testing systems is disclosed. In one embodiment, an offset is determined for correcting a time of flight measurement, wherein the offset is based on the pulse delays at first and second calibration temperatures. In another embodiment, a factor is determined for correcting a time of flight measurement, wherein the factor is based on clock signal errors at first and second calibration temperatures.
