    The stabilized contrast sensitivity of the human eye is tuned to specific spatial frequencies based on retinal velocity. This visual system characteristic is crucial for understanding how we perceive objects moving at different speeds.

    Area of Science:

    • Vision Science
    • Neuroscience
    • Perception

    Background:

    • The human visual system's contrast sensitivity is fundamental to visual perception.
    • Understanding how contrast sensitivity changes with object motion is essential for visual processing.

    Purpose of the Study:

    • To investigate the stabilized contrast-sensitivity function at constant retinal velocities.
    • To characterize the spatio-temporal threshold surface for stabilized vision.
    • To determine how visual perception adapts to different object motion speeds.

    Main Methods:

    • Measured contrast sensitivity at various constant retinal velocities.
    • Analyzed the Fourier transforms of constant-velocity passbands.
    • Constructed the spatio-temporal threshold surface by interpolating diagonal profiles.

    Main Results:

    • Stabilized contrast sensitivity is tuned to spatial frequencies inversely related to retinal velocity.
    • At low velocities (natural eye drift), results match unstabilized contrast sensitivity.
    • At higher velocities, the contrast-sensitivity curve shifts to lower spatial frequencies while maintaining its shape.

    Conclusions:

    • The spatio-temporal threshold surface for stabilized vision exhibits near-symmetry.
    • Visual system's spatial and temporal responses become largely independent at low spatial or temporal frequencies, respectively.
    • The visual system dynamically adjusts spatial frequency tuning based on object velocity for effective perception.
