    Area of Science:

    • Optics and Photonics
    • Biomedical Imaging
    • Spectroscopy

    Background:

    • Terahertz (THz) spectroscopy shows potential for diagnosing ocular diseases.
    • Current methods using Gaussian beams for cornea imaging have significant analysis errors (5-10%) due to beam-surface mismatch.

    Purpose of the Study:

    • To investigate the use of wavefront-modified vector beams for enhanced cornea spectroscopy.
    • To reduce analysis errors in terahertz spectroscopy of the cornea.

    Main Methods:

    • Developed a 3D Angular Spectrum Method for synthesizing vector beams with vector spherical harmonic presentation.
    • Performed wavefront modification and scattering analysis on 100-layer cornea models.
    • Compared the performance of spherical and cylindrical vector beams against Gaussian beams.

    Main Results:

    • Wavefront-modified spherical vector beams reduced analysis error to less than 0.5%, showing increased accuracy and non-sensitive focusing.
    • Wavefront-modified cylindrical vector beams exhibited frequency-dependent scattering, making them unsuitable for cornea spectroscopy.
    • Cylindrical vector beams show potential for optical force applications.

    Conclusions:

    • Wavefront-modified spherical vector beams offer a superior alternative to Gaussian beams for accurate cornea spectroscopy.
    • Vector beams have potential applications in medical imaging, optical tweezers, and other optical force applications.
