Apr 13, 2024 · Visible light communication (VLC) has emerged as a transformative technology that leverages light as a carrier for wireless data transmission. This chapter delves into the fundamentals of VLC, beginning with an insightful exploration of its background and...
VLC is a subset of optical wireless communications technologies. The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s over short distances.
flicker is defined as “perception of visual unsteadiness induced by a light stimulus the luminance or spectral distribution of which fluctuates with time, for a static observer in a static environment”. Consequently, flicker is only perceptible if the modulation frequency is below about 90 Hz. At higher frequencies our eyes
In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.
Visible light communication (VLC) is a wireless method that enables high-speed transmission of data with visible light. This data is transmitted by modulating the intensity of light given off by a light source.
