Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit ...

Abstract: The burgeoning technology of optical intelligent reflecting surfaces (OIRSs) offers significant potential within the realm of visible light communication (VLC) systems. This is primarily ...

Traffic lights are an integral part of maintaining order among vehicles, cyclists, and pedestrians. And while an agreement has been in place since the late 1960s standardizing intersection lights ...

Abstract: Visible light communication (VLC) is a promising technique in future networks due to its advantages of high data rate and licensed-free spectrum. In this paper, we apply the non-orthogonal ...
