摘要

A heterodyne interferometric system was used to detect the normal and tangential components of the displacement at one point of a sample when it is vibrating freely in its natural modes, arising from transient excitation. A cylindrical aluminium rod was the test sample. An analysis of the spectrum associated with the in-plane and out-of-plane displacements made it possible to determine the values of the longitudinal and transverse natural frequencies.
