摘要：
1. A dispersive shear wave (SDUV) vibrometry method, comprising: after a single pulse of their propagation (218) issuing a plurality of tracking pulses (222) for sampling, more than once, at each of a plurality of locations (120) on an associated monochromatic shear wave (116) when sampling, in which at least one of the scans for multiple locations is performed in separate passes and, with the issuance (612) of multiple tracking pulses, multiple samples are taken in multiple estopolozheniy.2. The method according to claim 1, further comprising: determining, at a given moment, the phase difference (140, 142) by taking into account delays between samples, if the determination is based on samples that, during said sampling, were taken at different points in time .3. The method according to claim 2, wherein said determination comprises calculating a specified difference using two samples taken at different points in time, and adding to the calculated difference based on the delay between the samples a phase correction (156) reflecting, for said monochromatic shear wave, propagation, which occurred between two samples. 4. The method according to claim 3, wherein said calculated difference and said correction are numbers opposite in sign (520) in the case when scanning from one of the two samples to the other takes place in the direction opposite to the direction in which the specified wave propagates. The method according to claim 3, wherein said correction is directly proportional to the angular frequency of the specified wave and the delay between taking two1.
