    This study introduces a new arctangent-based method for extracting phase shifts from nonsinusoidal fringe patterns. The technique enhances accuracy in real-world testing by overcoming limitations of traditional arccosine and arcsine algorithms.

    Area of Science:

    • Optical Metrology
    • Image Processing

    Background:

    • Real-world fringe patterns often exhibit nonsinusoidal intensity distributions.
    • Conventional phase shift extraction algorithms using arccosine or arcsine functions are sensitive to these deviations, impacting accuracy.

    Purpose of the Study:

    • To develop and validate a robust arctangent-function-based phase shift extraction algorithm.
    • To address the performance degradation of existing methods in nonsinusoidal fringe pattern analysis.

    Main Methods:

    • Constructing two orthogonal fringe patterns via subtraction and addition of background-removed images.
    • Normalizing fringe patterns to eliminate amplitude differences.
    • Determining phase shift by computing the norms of the normalized fringe patterns.
