ABSTRACT = {We propose a non-iterative approach to extract the unknown phase
shift in phase shifting interferometry without the assumption of equal distribution
of measured phase in [0, 2π]. According to the histogram of the phase difference
between two adjacent frames, the phase shift can be accurately extracted by finding
the bin of histogram with the highest frequency. The main factors that influence
the accuracy of the proposed method are analyzed and discussed, such as the random noise, the quantization bit of CCD, the number of fringe patterns used and the
bin width of histogram. Numerical simulations and optical experiments are also
implemented to verify the effectiveness of this method.},
