Yes, that's what I was referring to. If you have an edge flickering at a high frequency and perform a saccade (fast eye movement) over the edge, your retina will be exposed to the edge at regularly spaced intervals. So the motion will not appear smooth. That's what they call a 'flicker artifact' and I called a 'stroboscope-like effect'. Importantly though, this is not us humans detecting 500 Hz flicker itself, quite the opposite -- the reason the artifact is visible is that our retina is not sensitive to fast motion, it integrates over a period of time in which the edge appears to be in multiple locations. |
