INTRODUCTION Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to transmit data for telecommunications orcomputer networking. "Free space" means air‚ outer space‚ vacuum‚ or something similar. This contrasts with using solids such as optical fiber cable or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations. Free-space optical communication (FSO)

nahas | 4/29/2011 | | Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we introduce a free space optical communication system with dual wavelength

An optical illusion (also called a visual illusion) is characterized by visually perceived images or views that can differ a ton from objective reality. Optical illusions have been around for centuries‚ teaching us that you shouldn’t fully trust your senses due to that we can easily be tricked. However‚ optical illusions can help us learn how easy it is to trick our brain to see an object that seems real but is really not. An example of a well-known visual illusion would be the “Ames Room”.

Eutrophication Introduction Europhication (the over enrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem (Carpenter‚ 2005). The main cause is excessive loading into the system of phosphorus and nitrogen‚ resulting in high algal biomass‚ dominance by cyanobacteria‚ and loss of macrophytes (Dixit‚ 2005). When the nutrient concentrations rise to extremely high levels‚ eutrophication
