Abstract
A first application of the digital Hilbert transform for processing of laser Doppler vibrometer signals is considered. The possibility of vi bration amplitude measurement with a relation errors less than 1% in t he amplitude interval 0.1-10 Lambda, where Lambda is the fringe spacin g, and the linear velocity measurement of the examined object has been proved. The analysis of the amplitude measurement errors is given. Th e applications of the method under review are discussed. (C) 1998 Else vier Science Ltd. All rights reserved.
