Mueller matrix retrieval from intensity data is sensitive to noise. The discrete Fourier transform method offers superior stability and precision compared to classical matrix inversion techniques for accurate Mueller matrix element extraction.

Area of Science:

  • Optical physics
  • Metrology
  • Data analysis

Background:

  • Mueller matrix measurements are crucial for characterizing optical properties of materials.
  • Extracting Mueller matrices from intensity data is inherently challenging due to noise sensitivity.
  • The selection of a data processing method significantly impacts the accuracy of retrieved Mueller matrix elements.

Purpose of the Study:

  • To evaluate the robustness of different Mueller matrix retrieval methods against noise.
  • To compare the precision of classical matrix inversion versus discrete Fourier transform approaches.
  • To identify the most stable and accurate method for Mueller matrix element extraction.

Main Methods:

  • Synthesized computer data with added Gaussian noise was used to test method robustness.

  • Experimental data was utilized for verification of the tested methods.
  • Three distinct Mueller matrix retrieval algorithms were analyzed.

    • Main Results:

    • Classical matrix inversion methods demonstrated limited noise reduction capabilities, even with increased data.
    • The discrete Fourier transform approach exhibited exceptional stability when subjected to noise.
    • The superior performance of the discrete Fourier transform method is attributed to its inherent filtering properties.

    Conclusions:

    • The discrete Fourier transform method is a highly stable and precise technique for Mueller matrix retrieval.
    • For noise-sensitive Mueller matrix measurements, the discrete Fourier transform approach is recommended.
    • Understanding the impact of noise and method choice is critical for accurate optical characterization.
