FlickerFusionfrequenz

FlickerFusionfrequenz, often abbreviated as FFF, refers to the threshold at which a flickering light source appears as a continuous, steady illumination to the human eye. This phenomenon is a result of the persistence of vision, a biological process where the image of an object remains in the eye for a brief period after the object is no longer present. When the rate of flicker, or the number of light interruptions per second, exceeds the FlickerFusionfrequenz, the visual system cannot distinguish between individual flashes and perceives a continuous light.

The FlickerFusionfrequenz varies among individuals and can be influenced by factors such as age, ambient light conditions, and the intensity of the light source. For a typical adult, this frequency is generally in the range of 50 to 90 Hz. This principle is fundamental to the operation of many technologies, including cinema, television, and computer monitors. For instance, the high refresh rates of modern displays, typically 60 Hz or higher, ensure that the images appear smooth and free of noticeable flicker, contributing to a comfortable viewing experience. Understanding FlickerFusionfrequenz is crucial in fields like visual ergonomics and the design of visual displays to prevent eye strain and visual fatigue.
