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

fibre optic transmitter that are in use today. Both of them are based around semiconductor technology: • Light emitting diodes (LEDs) • Laser diodes Semiconductor optical transmitters have many advantages. They are small‚ convenient‚ and reliable. However‚ the two different types of fibre optic transmitter have very different properties and they tend to be used in widely different applications. LED transmitters These fibre optic transmitters are cheap and reliable. They emit only incoherent light

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

Optical Distortion‚ Inc. case Daniel Garrison‚ the president and CEO of Optical Distortion‚ is thinking about to bring the new and only product‚ a contact lens for chickens‚ to the markets. Working with Ronald Olson‚ the marketing vice president‚ Garrison is currently developing a marketing plan for ODI’s new product. ODI is planning to introduce these contact lenses to at least one region at the beginning‚ hoping to reach national distribution in a couple of years. There are three different sizes

SITUATION ANALYSIS: Optical Distortion Inc.(ODI) markets lenses that distort the vision of chickens. These lenses are used instead of debeaking. Lensed chickens are more likely to survive from cannibalism among the chickens. The lenses are also supposed to reduce the amount of feed per chicken per day than that for debeaked chickens. Using lenses do not lead to any trauma among chickens and therefore do not affect their egg laying capacity. The objective of the case is to present a financial

What Causes Optical Illusions? Optical illusions are how the eye sees the illusion. Most people now believe that seeing optical illusions has to do with perspective‚ or the way you look at something. The concept of optical illusion was first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. We get used to how things are supposed to be‚ and sometimes our brain gets the wrong message. Our brain puts

DESCRIPTION OPTICAL MICROSCOPE Introduction The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology‚ microbiology‚ biotechnology‚ pharmacology‚ forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words‚ Optical microscope
