What is TLA (Temporal Light Artifacts) ?
An undesired change in visual perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time, for an observer in a certain environment.
|Name||Definition(CIE)||Frequency Range||Environment||Observer (Human)||Illustration||Metrics|
|Flicker||Perception of visual unsteadiness induced by a light stimulus whose luminance or spectral distribution fluctuates with time, for a static observer in a static environment.||~0 - 80Hz||Static||Static|
No motion (see it when nothing is moving)

|Stroboscopic Effect||Change in motion perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time, for a static observer in a nonstatic environment.||~80Hz - 2kHz||Dynami||Static|
Object motion (see it when object is moving and you are not)
|Phantom Array Effect||Perception of a spatially extended series of light spots when making a saccade (image transition across the retina) across a light source that fluctuates with time.||~80Hz - 2kHz||Static||Dynami|
Eye motion (see it when your eye is moving and object is not)
