Abstract: A calibration system is provided for calibrating acoustic transducers such as phased array acoustic transducers and time of flight acoustic transducers. In one embodiment, a calibration block is provided with predetermined calibration features defined therein. The calibration block may be provided with guide surfaces or engagement surfaces utilized to position the transducers accurately with respect to the calibration features so that the same acoustic scanning views are consistently produced. In one embodiment, the guide surfaces define a recessed region for acoustic couplant. The outputs can be combined to produce an image and compared to a known image to verify that the acoustic transducers are all oriented properly and calibrated for operation.

Abstract: A calibration system is provided for calibrating acoustic transducers such as phased array acoustic transducers and time of flight acoustic transducers. In one embodiment, a support frame for a plurality of acoustic transducers may be used to calibrate the transducers simultaneously. The support frame is modular and can be customized with respect to its overall configuration, the number of transducers, and the placement of the transducers. Groups of transducers may be added or removed as well as individual transducers. The outputs of the acoustic transducers are collected as the acoustic transducers are simultaneously moved and/or positioned. The outputs can be combined to produce an image and compared to a known image to verify that the acoustic transducers are all oriented properly and calibrated for operation.
