    This study introduces a novel visualization method for phase changes in 2D objects using half-order differentiation filters. The technique enhances phase visibility by processing spatial frequencies, proving effective for gradient-index materials.

    Area of Science:

    • Optics
    • Image Processing
    • Materials Science

    Background:

    • Phase changes in pure-phase objects are difficult to visualize directly.
    • Traditional methods often struggle with the limitations of square-law detection.

    Purpose of the Study:

    • To present a new method for visualizing phase changes in 2D pure-phase objects.
    • To demonstrate the effectiveness of half-order differentiation filters for phase visualization.

    Main Methods:

    • Utilizing two orthogonal Fourier plane filters to perform half-order differentiation.
    • Applying real semiderivative filters sequentially in two dimensions.
    • Employing nonlinear filtration of spatial frequencies.

    Main Results:
