Va. Grechikhin et Bs. Rinkevichius, HILBERT TRANSFORM FOR PROCESSING OF LASER-DOPPLER VIBROMETER SIGNALS, Optics and lasers in engineering, 30(2), 1998, pp. 151-161
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
