This study introduces a new 2D wavelet transform (WT) daughter wavelet for optical fringe pattern analysis. The advanced WT coefficients reliably represent phase data reliability, improving optical metrology accuracy.

Area of Science:

  • Optics and Photonics
  • Signal Processing
  • Image Analysis

Background:

  • Optical fringe pattern analysis is crucial for metrology.
  • Existing 2D wavelet transform (WT) methods using common daughter wavelets struggle to accurately represent phase data reliability.
  • The modulus of WT coefficients is used to assess phase data quality.

Purpose of the Study:

  • To theoretically discuss the modulus of 2D WT coefficients for optical fringe pattern analysis.
  • To evaluate the performance of two common 2D daughter wavelet definitions.
  • To propose a novel 2D daughter wavelet definition for improved reliability-guided phase unwrapping.

Main Methods:

  • Theoretical discussion of the modulus of 2D WT coefficients.
  • Analysis of two frequently used 2D daughter wavelet definitions.

  • Development and application of a new 2D daughter wavelet definition.
  • Computer simulations and experimental validation.

    • Main Results:

    • Neither of the two common 2D daughter wavelet definitions adequately represents phase data reliability.
    • The proposed new 2D daughter wavelet definition yields WT coefficients containing both modulation and local frequency information.
    • The modulus of the advanced 2D WT coefficients serves as a reliable indicator of retrieved phase data quality.

    Conclusions:

    • A new 2D daughter wavelet definition is proposed for enhanced optical fringe pattern analysis.
    • The proposed method improves the reliability of phase data by incorporating local frequency information.
    • Computer simulations and experiments confirm the validity and effectiveness of the new wavelet definition.
