Abstract

An implementation of the phase shifting technique for computer aided processing of interference fringes obtained by the moiré interferometry method for in-plane displacement measurements is described. The polarized light is used for both the temporal and spatial ( multichannel ) approaches. The latter one enables to work at single frame rate. The experimental results obtained serve the comparison of the two approaches.
