This paper presents the methods of linear interpolation and polynomial curve fitting for achieving subpixel resolution in phase difference determination by fringe pattern matching. These two methods were examined by computer simulation and experiment. In computer simulation, the effects of the resolutions of imaging system were also discussed. The computer simulation and experimental results have shown that the method of linear interpolation and that of polynomial curve fitting can both be used to achieve sub-pixel resolution in the measurement of phase difference by fringe pattern matching. The phase difference between fringe patterns is easy to achieve by linear interpolation compared with polynomial curve fitting.
