FREE OPTICS. Free space optics or FSO –Although it only recently and rather suddenly sprang in to public awareness‚ free space optics is not a new idea. It has roots that 90 back over 30 years-to the era before fiber optic cable became the preferred transport medium for high speed communication. FSO technology has been revived to offer high band width last mile connectivity for today’s converged network requirements. 101seminartopics.com FSO ! FREE SPACE OPTICS Free space optics or FSO

Objective The objective of this experiment was to find the focal length of two converging lenses separately and also to find the focal length of combination of two converging lenses. Another objective was to study the image formed by a converging lens plus diverging lens. Background This experiment focused on a simple lens system. A simple lens is a piece of glassware that is spherical on one side and flat on another side‚ or spherical on both sides. There are two different types of lenses

Isaac Newton was one of the most influential people of the Scientific Revolution. His ideas are framework for modern physics and forever changed what science is and how it’s conducted. Newton believed that all natural philosophy and phenomena could be explained by science and he set out to do just that throughout his life. He did research in optics‚ created the theory of universal gravity‚ wrote the three laws of motion‚ invented calculus and he was even able to calculate the shape of the earth.

to keep out stray light. The light is then reflected off a concave mirror composed of “ultra-low expansion glass” that is constantly kept at room temperature. The mirror was ground to have reflecting surfaces of the precise shape (“Hubble’s Amazing Optics”). The Hubble Space Telescope has a focal length of 189 feet (Elert). In 1993 the Hubble Telescope was surpassed by the Keck Observatory Telescopes located in Mauna Kea‚ Hawaii (Moseman). The twin telescopes both hold a 33-foot in diameter mirror

Influences of Fiber Optics Introduction: People have been trying to improve communications over the centuries. Communication plays a very important role in everyday life. The advancement of the world mostly depends on how we share the information with the rest of the world. Fiber optics is making this task easier and quicker. It is currently the fastest internet technology. Fiber optic is a technology of transmitting light through very thin flexible glass or plastic fibers. It is one of the fastest

Fiber optic communication ABSTRACT FIBRE-OPTICS COMMUNICATION Most reference materials that discuss the historical perspective mention about Indian smoke signals. None of these primitive systems was secure due to the spreading of the unguided light. Ideally‚ a communication system should be secure and should not require installation of a cumbersome physical media. Fiber optics satisfied these desires‚ and as early as 1958‚ fiber-optic equipment was being focused for use in the factory. The fiber-optic

attempts of Wong’s team to launch new product crushed. First of all‚ it can be because of false assumptions (“dangerous assumptions”) that were made by team. That’s why we can conclude that level of uncertainty for new security screeen is rather high and Optic System doesn’t see all opportunities and threats. There is no relevant marketing research for new product. Two main advantages that were found by Noirjean are not sufficient to beat competitors. So‚ it can be that two risks “Existing Competition” and

Chapter 14 Outline I. Refraction of Light A. Refraction is the bending of light at the boundary of two media. 1. It is caused by differences in the way light travels in the two media a) Light changes speed unequally. (1) One side of the light becomes slower/faster 2. If light is perpendicular to the new medium‚ light will not refract a) If the media have the same index of refraction‚ light will not refract B. Index of Refraction 1. How well light travels through a medium is measured by
