发明名称 Acoustic transducer calibration block and method
摘要 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.
