摘要
本文提出了一种用连续激光器,在时间相关理论依据下,以电光相位调制显示超声行波波前的新方法;并考虑到运动相位和静止相位的差异,提出了一种特殊的空间滤波技术,从而显示了超声行波的高对比像.
A new method to display ultrasonic traveling wavefront by electrooptio modulator based on temporal correlation theory using CW laser has been developed, and high contrast image of ultrasonic traveling wavefront has been showed by special filtering technique based on considering the defference between moving phase objects and static phase objects.
