The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .
An internet version of the CDR system is available using keyboard commands to measure responses. Ancillary equipment is used for specific cognitive tests such as a postural stability (sway) meter, a critical flicker fusion device or joysticks for CDR's tracking test.
Flicker perception. Binocular summation can increase the critical flicker fusion rate (CFF) which is the highest perceivable flicker rate before the image appears continuous. The CFF is increased when both eyes see the same flicker, and it is decreased when the flicker for one eye is out of phase with the other.
Up to about 80 Hertz or the flicker fusion threshold it is called visible flicker. From about 80 Hertz to 2000 Hertz it is called the stroboscopic effect (this article). Overlapping in frequency, but from 80 Hertz up to about 6500 Hertz a third effect exists called the phantom array effect or the ghosting effect , an optical phenomenon caused ...
Running the numbers before the first 2.2 MJ fusion test, NIF scientists projected the energy yield could hit around 10 MJ, three times more than the previous year’s shot had produced—assuming ...
