Phi flicker phenomena
WebMax Wertheimer WebAbstract:Voltage flicker has emerged as a major concern problem in the area of power quality. Amongst its effects, it is recognised that, in addition to the visual inconvenience, several types of electrical equipment can be strongly disturbed.

The term phi phenomenon is used in a narrow sense for an apparent motion that is observed if two nearby optical stimuli are presented in alternation with a relatively high frequency. In contrast to beta movement, seen at lower frequencies, the stimuli themselves do not appear to move. Instead, a diffuse, amorphous shadowlike something seems to jump in front of the stimuli and occlude them temporarily. This shadow seems to have nearly the color of the background.

The event-related potentials exhibited steady-state oscillations at all frequencies up to at least 90 Hz. Interestingly, the steady-state potentials exhibited clear resonance phenomena around 10, 20, 40 and 80 Hz. mudding over screwsWebPhi phenomenon essentially forms the basis for which motion pictures are designed and produced from.
