Paper Abstract

Noise reduction is one of the largest problems and biggest difficulties involved in electronic speckle pattern interferometry. We present the new filtering method for electronic speckle pattern interferometry fringes (ESPIF) images based on Markov chain Monte Carlo methods. We test the proposed method on the computer-simulated speckle fringe patterns and an experimentally obtained fringe pattern, respectively. In all cases, the proposed method gives desired results. Experimental results have confirmed that the proposed method is capable of removing noise in ESPIF images effectively and enhancing the contrast of fringe patterns.
