Exploring the Hidden World of Lighting Flicker with a High-Speed Camera

open access: yesAtmosphere
Alternating current can result in flickering—or pulsing—in the brightness of light emitted by luminaires. Lighting flicker typically occurs in the range of 100 to 140 cycles per second (Hz), which is too fast for visual perception by most organisms ...
