Paper Abstract

Holographic interferometry in Fourier plane allows 3D displacement measurement from one recording, with fringe localization in Fourier plane and with the interpretation of only two type of fringe patterns. The measuring range can be controlled by the parameters of the Fourier lens and covers units to hundreds micrometers. Such a Fourier holographic processor with real-time recording is very suitable for interfacing to a computer image processor which works for automatic interpretation of the holographic interferograms and precise measurement.
