Abstract

First application of Digital Hilbert Transform for processing of Laser Doppler Vibrometer signals is considered. The possibility of the vibration amplitude measurement with relation errors 1 divided by 5% in the amplitudes interval 0.1 (Lambda) divided by 10 (Lambda) , where (Lambda) is the fringe spacing, and the linear velocity measurement of the examined object has been proved. The analysis of the amplitude measurement errors is given. The applications of the method under review are discussed.
