摘要:
本文简单介绍了超声渡越时间的测量。采用连续正弦波,用低速器件建立了超声渡越时间测量系统。对系统进行了说明,引入特征参量描述矢量电压表的状态,对状态进行自动识别。提出相位跟踪法、预测校正方法,实现微机控制渡越时间快速自动测量,作为例子,给出由测量渡越时间而得到的水的声速测量值和琼脂模型的超声声速断层图象。
Abstract:
In this paper, the measurement of ultrasonic flight-time is briefly discussed. The system for measuring ultrasonic flihgt-time by continuous sine wave has built with low speed equipment. The system is also explained. To describe the states of the vector voltmeter, characteristic parameters are lead to the system. Methods of track-phase and forecast-correction are proposed to fast automeasure ultrasonic flight-time under the control of microcomputer. As the examples of application, ultrasonic velocity in water and ultrasonic CT with velocity is given by mearsuring ultrasonic flight-time.
