Intentional light variations are applied for warning, signalling (e.g. Light emitted from lighting equipment such as luminaires and lamps may vary in strength as function of time, either intentionally or unintentionally. In general, undesired effects in the visual perception of a human observer induced by light intensity fluctuations are called Temporal Light Artefacts] (TLAs). The visibility aspects of flicker are given in a technical note of CIE see CIE TN 006:2016. Adverse effects of flicker of include annoyance, reduced task performance, visual fatigue, headache and epileptic attack by photosensitive persons. Various scientific committees have assessed the potential health, performance and safety-related aspects resulting from temporal light modulations ( TLMs) including light flicker. 5 Publications of standards development organisations.įlicker due to mechanical factors such as AC line frequency (typically 50 or 60 Hz) will have a stable frequency structure, whereas the flicker of a damp or failing light bulb will often have a chaotic or erratic frequency structure. Due to the flicker fusion threshold of foveal vision, steady vision can rarely detect flicker above 90 Hz, whereas flicker can be perceived during visual saccades up to or beyond 1 kHz. The spectral sensitivity of the human eye to flicker depends upon the mode of visual perception.
Shutter speeds used in motion photography can interact with high frequency flicker to produce visual artifacts in the captured imagery that betray flicker that would not otherwise be noted. Light meters and image sensors can potentially detect flicker at much higher frequency bands than human vision. Twinkling, also called scintillation, is a generic term for variations in apparent brightness, colour, or position of a distant luminous object viewed through a medium.įlicker exists for other organisms having different perceptual thresholds.
