WebWhat is critical fusion frequency? Critical flicker/fusion frequency (CFF) is the transition point for an intermittent light of increasing temporal frequency, where the flickering ceases and the light is perceived as continuous. If the light’s modulation depth is high, then CFF is the temporal equivalent of a visual acuity measurement.
