IDEA #7172DR Method and system for correcting for temperature variations in ultrasonic testing systems

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. https://app.acclaimip.com/pdf/fdagdnHldIxC1qATlOV0gCkE38vCMr5oh69m23w/US8997550B2
