Visual Deception Visual phenomena or what we normally call as ‘Optical Illusion’ involves visual deception. A wide range of optical illusions happen in our day to day lives‚ like seeing a rainbow after a rainy day or even while staring at clouds; In this phenomenon‚ the human brain tends to develop different pictures to interpret the shape‚ curve‚ and size of the clouds. Optical illusions are just cases of errors in judgment; they do not physically exist. Our eyes capture light from

nonlinear effects and cost. The idea of dispersion compensation using chirped fiber gratings was firstly proposed by Qulette [4] and later demonstrated experimentally by Williams et.al. [5]. A fiber Bragg grating is a reflective device composed of an optical fiber that contains a modulation of its core refractive index over a certain length. The grating reflects light propagating through the fiber when its wavelength corresponds to the modulation periodicity. In a chirped FBG‚ the periodicity of the induced

orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The purity of the oil extracted from the oranges can be determined by physical properties such as optical rotation and refractive index. In this experiment‚ limonene will be isolated by steam distillation. Normally‚ big molecules such as limonene require very high temperatures to boil. In the presence of water‚ liquids which are immiscible with water

heat-resistant glass in 1908. In 1912‚ this product was being reused to develop the shatterproof lanterns for the railroad. Their products were first used for scientific purposes and later for consumer cook-ware products. By realizing the improvement in optical glassmaking‚ Corning had started to produce the television tubes project and it made the TV affordable to the consumers’ market during 1970s. However‚ this project considered a steep loss in profit and productivity because of the competition from

as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser or LED. This travels along the cable by means of Total Internal Reflection‚ bouncing from one side of the glass’s inner surface to another and therefore following the cable’s path. Bandwidth Although new techniques may allow copper cables to carry much more data than in the past‚ in most cases optical fibers provide much greater bandwidth. The first generation of
