Sentence examples for fusion frequency from inspiring English sources

"People have shown in humans that flicker fusion frequency is related to a person's subjective perception of time, and it changes with age.

"Critical flicker fusion frequency" – the point at which the flashes seem to merge together, so that a light source appears constant – provides an indication of time perception.

This latter type of contraction is called a fused tetanus, and the rate of stimulation that produces it is called the fusion frequency.

If the sector rotates slowly, a sensation of black followed by white is aroused; as the speed increases the sensation becomes one of flicker i.e., rapid fluctuations in brightness; finally, at a certain speed, called the critical fusion frequency, the sensation becomes continuous and the subject is unaware of the alterations in the illumination of the screen.

At high levels of luminance, when cone vision is employed, the fusion frequency is high, increasing with increasing luminance in a logarithmic fashion the Ferry-Porter law so that at high levels it may require 60 flashes per second to reach a continuous sensation.

Devices with such a high frame rate are not commercially available, but are required, if sensory systems with high flicker fusion frequency are to be studied.

The experimental data, such as the search time, accuracy rate, critical fusion frequency (CFF), and subjective visual fatigue, were recorded in the database as well as analyzed.

Jackson and his colleagues demonstrated this with a phenomenon called "critical flicker fusion frequency," which is based on the maximum speed of flashing lights an animal can see before it just looks like a steady, constant light — the same principle behind the illusion of non-flickering television.
