Abstract: A noise-immune method for phase retrieval of a single moiré interferometric fringe pattern is presented and discussed. The method is shown to provide accurate recovery of the phase information by a combined method based on modification of the local intensity histogram and use of a two-dimensional Fourier transform of the enhanced moiré fringe pattern. The principle of the method is described and the experimental results of moiré interferometric measurements with submicrometre sensitivity of the in-plane displacement fields of thick carbon fibre/PEEK composite laminates are presented as an example of the application of the technique.
