Abstract
An ultrasound method of measuring displacement with high resolution includes transmitting a pair of Golay's complementary sequences or other complementary sequences, receiving echoes from the object and performing pulse compression of the two sequences of echoes. The displacement of the object between the two transmissions is derived from the residual clutter signals around the mainlobe of the compressed pulse output. Furthermore, movement velocity, thickness, strain, elastic stiffness, and viscous damping of the object or regions of the object can be determined subsequently.
