    Summary
    This summary is machine-generated.

    This study introduces a spatial pattern-shifting method (SPSM) for two-wavelength fringe projection profilometry (FPP). The SPSM maximizes the unambiguous phase range (UPR), overcoming limitations with non-coprime wavelengths for enhanced 3D shape measurement.

    Area of Science:

    • Optical Metrology
    • 3D Shape Measurement
    • Computational Imaging

    Background:

    • Two-wavelength fringe projection profilometry (FPP) is crucial for accurate 3D shape measurement.
    • The unambiguous phase range (UPR) in FPP is typically limited by the least common multiple (LCM) of the wavelengths.
    • Using non-coprime wavelengths in FPP restricts the UPR, compromising measurement performance.

    Purpose of the Study:

    • To propose a novel spatial pattern-shifting method (SPSM) for two-wavelength FPP.
    • To enable the generation of the maximum UPR (product of wavelengths) even with non-coprime wavelengths.
    • To overcome the constraint of wavelength selection in two-wavelength FPP.

    Main Methods:

    • Implementation of a spatial pattern-shifting method (SPSM).
    • Spatially shifting a low-frequency pattern by designed amounts.
    • Adjusting fringe order determination based on spatial shifts.

    Main Results:

    • The SPSM successfully generates the maximum UPR from two non-coprime wavelengths.
    • This method breaks the constraint of wavelength selection for complete two-wavelength FPP.
    • Numerical and experimental analyses confirmed the flexibility and correctness of the SPSM.

    Conclusions:

    • The proposed SPSM significantly enhances the performance of two-wavelength FPP.
    • It allows for complete FPP using any combination of two wavelengths, including non-coprime pairs.
    • The method offers a convenient and robust solution for 3D shape measurement challenges.
