    This study introduces an electro-optical eye-tracker that stabilizes laser beams on the retina by precisely measuring and compensating for eye movements. The system achieves high accuracy, keeping beams within +/-10 micrometers of the target fundus feature.

    Area of Science:

    • Ophthalmology
    • Biomedical Engineering
    • Optical Engineering

    Background:

    • Accurate stabilization of optical beams on the retina is crucial for various ophthalmic procedures and research.
    • Fixational eye movements can introduce significant instability, compromising precision.

    Purpose of the Study:

    • To develop and evaluate an electro-optical eye-tracker for one-dimensional laser beam stabilization on the human fundus.
    • To assess the system's ability to compensate for typical fixational eye movements.

    Main Methods:

    • Utilized laser illumination of a fundus feature to detect motion.
    • Employed an intensified linear CCD camera to image the illuminated area.
    • Developed electronics to determine the image intensity centroid for real-time eye movement tracking.

  • Implemented galvanometer-controlled mirrors for high-speed (1-kHz) beam repositioning.

    • Main Results:

    • The eye-tracker successfully detected and compensated for eye movement in one dimension.
    • The system maintained laser beam stabilization on the fundus feature within +/-10 micrometers for typical eye movements.
    • Additional beams were also stabilized concurrently.

    Conclusions:

    • The developed electro-optical eye-tracker provides effective and precise stabilization of laser beams on the retina.
    • This technology has potential applications in improving the accuracy of ophthalmic diagnostics and treatments.
