Foundations of Vision, Sinauer Associates, Inc., Sunderland, Massachusetts (1995) Wandell makes reference to studies showing that, at high ambient light levels, the highest detectable spatial frequency is 50 to 60 cycles per degree (cpd). Since there are 60 minutes of arc in one degree of arc, this says we need two digital samples (one for the black bar of the cycle and one for the white bar of the cycle) in one minute of arc or 120 of them in one degree of arc. This is reasonably consistent with the optometrists’ metric, which is based on visual perception under normal light conditions
