High Accuracy Ultrasound Micro-Distance Measurements with PMUTs under Liquid Operation
Ultrasonic systems driven by multi-frequency continuous waves (MFCW) have been used for range distance measurement, offering high accuracy in long and medium range distance estimation. However, the use of continuous waves in very short-distance measurements causes large errors due to multipath refle...
