FLICKER FUSION Meaning and
Definition
-
Flicker fusion, also known as the flicker fusion threshold or critical flicker fusion, refers to the minimum frequency at which a flickering light source appears steady or continuous to the human eye. It is a perceptual phenomenon that determines the rate at which the human visual system can integrate intermittent visual stimuli into a single coherent perception, without perceiving any flickering or disruption.
The concept of flicker fusion is particularly relevant in studies related to visual perception, lighting technology, and motion picture frame rates. The individual flicker fusion threshold can vary among individuals and is influenced by factors such as age, lighting conditions, and the size and brightness of the light source.
In practical terms, the flicker fusion threshold is often measured by increasing the frequency of a flickering light until it is perceived as steady by the viewer. This frequency, known as the flicker fusion rate, is considered the minimum rate at which the light stimulus becomes indistinguishable from a continuously illuminated light source.
Understanding the flicker fusion threshold is crucial in various fields. For instance, in cinema, it helps determine the optimal frame rate for creating a smooth and natural motion perception for viewers. Additionally, it is also relevant in applications such as LED lighting design to avoid potential flickering effects that may cause visual discomfort or even impairment.

Etymology of FLICKER FUSION
The word "flicker fusion" is derived from two components: "flicker" and "fusion".
1. Flicker:
- Etymologically, "flicker" is derived from the Middle English word "flikeren", which means to flutter or flap.
- It is related to the Old Norse word "flikra", which also means to flutter.
2. Fusion:
- "Fusion" has its origins in the Latin word "fusio", which means a pouring or melting together.
- The Latin word is derived from the verb "fundere", which means to pour.
When combined, "flicker" and "fusion" represent the concept of the flicker fusion threshold, which refers to the minimum frequency at which a flickering light appears to be a continuous light to a human observer.
