“…1 5 "1 6 Two-photon absorption can be ruled out as a factor on the following grounds. Visual pigments would fluoresce as a result of two-photon absorption.16"1 7 This fluorescence would be at a longer wavelength than the second harmonic. The mixture of these two lights would always be matched to a wavelength longer than the second harmonic, which is inconsistent with the measurements presented in Table I.…”

“…Most of the work that established the Talbot-Plateau principle as a "law" was done in the early part of the 20th century (Bartley, 1937(Bartley, , 1938a(Bartley, , 1938b(Bartley, , 1939Beams, 1935;Gilmer, 1937;Hyde, 1906;Sherrington, 1902Sherrington, , 1904. Many investigators replaced the spinning mirror with spinning disks that had open sectors that could more precisely determine the duration of successive flashes.…”

The Talbot–Plateau law specifies what combinations of flash frequency, duration, and intensity will yield a flicker‐fused stimulus that matches the brightness of a steady stimulus. It has proven to be remarkably robust in its predictions, and here we provide additional support though the use of a contrast discrimination task. However, we also find that the visual system can register flicker‐fused letters when the combination of frequency and duration is relatively low. The letters are recognized even though they have the same physical luminance as background. We hypothesize that the letters elicit synchronous oscillations that encode for stimulus attributes, which prevents the letter from blending into the background.

“…He provided minimal details about experimental methods, and did not report any data other than saying that the principle was supported for flash durations ranging from 10 −6 to 10 −8 . Gilmer (1937) conducted two experiments, one that produced flash sequences with a rotating mirror and the other with a rotating disk. Intensity of the steady source was adjusted using Nicols filters.…”

The Talbot-Plateau law asserts that when the flux (light energy) of a flicker-fused stimulus equals the flux of a steady stimulus, they will appear equal in brightness. To be perceived as flicker-fused, the frequency of the flash sequence must be high enough that no flicker is perceived, i.e., it appears to be a steady stimulus. Generally, this law has been accepted as being true across all brightness levels, and across all combinations of flash duration and frequency that generate the matching flux level. Two experiments that were conducted to test the law found significant departures from its predictions, but these were small relative to the large range of flash intensities that were tested.
