Abstract
A video measuring installation for registering lowfrequency acoustic vibrations in two orthogonal directions with conversion of the results into a WAVform at file is described. The capabilities of the system in the detection of test mechanical vibrations at a frequency of 300 Hz were experimentally studied. The reso� lution of the system is 3 µm, and its dynamic range is 23 dB. The installation can be used in studies of vibra� tions of engineering and natural objects.
