  • Materials Engineering and Automatic Control
    Although the range can reach hundreds of meters , but the accuracy only reaches cm magnitude. By analyzing the causes of ultrasonic ranging error, using temperature compensation, and improving the measurement time difference to the microsecond level, ultrasonic distance measurement circuit can achieve millimeter-level accuracy.
  • Recent Advances in Mechatronics
    For instance, phase shift measurement for single test frequency of 40 kHz and distance between transducer and receiver about 0.1 meter required a FPGA-based digital phase detector [2]. The modern microcontrollers with fast built-in counters and timers make possible to construct an ultrasonic thermometer without the FPGA circuits .
