Design and Fabrication of a Laboratory Model Free Space Optical Link

Abstract

Free Space Optics (FSO) technology is an alternative broadband Technology, which provides fast, secure and reliable data transmission. The FSO systems are being used for commercial systems between fixed sites and are being considered for military systems because of their inherent benefits, which are security and high data rates. The small divergence of the laser beam makes FSO systems more secure than the existing radio frequency (RF) based wireless systems, because it is highly difficult to detect and intercept a laser beam due to the nature of the laser and the small divergence angle of the transmitter. However, FSO implementation on mobile platforms such as ships is still challenging. The benefits and challenges of FSO technology are also studied. We create the artificial environment in a box by using fog machine, fan heaters etc. and then check the attenuation of laser light..
