Abstract When a continuous or pulsed wave of ultrasound is scanned over an object, an echo emanating from the object may be detected. If the echo has a random variation in amplitude vs. position of the beam, the resulting variation is referred to as acoustical speckle. An analysis is presented for utilizing acoustical speckle to determine displacements on the surface or interior of an object. Two experimental configurations, pulse-echo and continuous wave scanning, are treated in the verification of the analysis.
