Solar fiber optic lighting for daylighting of high-rise intensive buildings and military shelters

solarlighting

Conventional daylighting scheme employing windows and skylights are no longer so useful especially for daylighting of high-rise and intensive buildings. Residential buildings with limited natural lighting are generally lit by fuel-based electricity which contributes to increase of CO2 concentration in…...

Hybrid Free Space Optics (FSO)/Radio Frequency (RF) communication systems can improve the performance of Free space optical communications

Hybrid FSO RF communication system

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight…...
