    Area of Science:

    • Ophthalmology
    • Vision Science
    • Biophysics

    Background:

    • Optical blurring affects standard contrast sensitivity measurements.
    • High spatial frequencies challenge existing vision testing methods.

    Purpose of the Study:

    • To develop a contrast sensitivity measurement technique less susceptible to optical blurring.
    • To investigate the foveal cone mosaic using a novel moiré pattern analysis.

    Main Methods:

    • Utilized an improved laser interferometer for forced-choice contrast sensitivity measurements.
    • Analyzed observer reports of visual patterns at high spatial frequencies (above 60-70 c/deg).

    Main Results:

    • A moiré pattern, resembling zebra stripes, was observed at high spatial frequencies.
    • This pattern is hypothesized to result from aliasing by the foveal cone mosaic.
    • The moiré pattern's characteristics correlate with foveal lattice regularity and cone spacing.

    Conclusions:

    • The developed laser interferometer provides robust contrast sensitivity data.
    • Moiré pattern analysis offers a new method to assess the foveal cone mosaic's properties.
    • This technique can evaluate cone spacing and light-catching area in the human fovea.
