Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

750
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

    Area of Science:

    • Optical Metrology
    • Image Processing

    Background:

    • Electronic Speckle Pattern Interferometry (ESPI) is a widely used technique for non-contact surface measurement.
    • Extracting accurate phase information from ESPI fringes, especially noisy or low-quality ones, remains a challenge.

    Purpose of the Study:

    • To propose a novel phase extraction method for single electronic speckle pattern interferometry (ESPI) fringes.
    • To address the limitations of existing methods in handling poor-quality fringe patterns.

    Main Methods:

    • Utilizing partial differential equations (PDEs) for fringe skeleton extraction and phase interpolation.
    • Employing an anisotropic PDE to adjust the gradient vector field (GVF) of the fringe.
    • Extracting fringe skeletons by combining the divergence property of the adjusted GVF.
    • Interpolating whole-field phase information using the heat conduction equation after assigning skeleton orders.

    Main Results:

    • Successfully extracted phase information from computer-simulated and experimental ESPI fringe patterns.
    • Demonstrated the effectiveness of the proposed PDE-based method in handling poor-quality fringe data.
    • Validated the accuracy and robustness of the phase reconstruction.

    Conclusions:

    • The proposed PDE-based method offers a robust solution for phase extraction in ESPI.
    • This technique significantly improves the reliability of phase retrieval from challenging fringe patterns.
    • The method has potential applications in various fields requiring precise surface metrology.
