Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope, uteroscope or a rectoscope showing the illuminating path, the image path, transmission path and the liquid transfer or operating instrument ducts, showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such fibres are used in medicinal
taking pictures on Earth, astronomers have to deal with many issues with distortion when it comes to taking images. The solution to this issue is a technology called adaptive optics (often referred to as AO), which was originally used to improve the performance of optical systems on ground based telescopes. [1] Adaptive optics are made up of mirrors, that can be reshaped that are controlled by computers. These mirrors fix the distortion caused by the turbulence of the Earth’s atmosphere. This makes
Fiber optics Thesis: Some of the important features of the fiber optics that we are interested are discussed below. Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size. Fiber optics are used mainly to use effectively its high bandwidth. On a single fiber lots of information/data can
Fiber Optics What are Fiber Optics? Fiber optics are thin transparent fibers of glass or plastic enclosed by a material of a lower index of refraction and that transmit light throughout their length by internal reflections. Real fiber optic cables are made out of very pure glass, glass so pure that if it were miles thick, light would still be able to pass through. The fiber optic strand, although thin in diameter, is stretched to miles in length. Therefore only the purest of glass would be
Atmospheric Optics Light is all around us, from both natural and artificial sources, during the day and the night. We think we understand it, and that what we see by it is an exact representation of what we are looking at. However we can be mistaken; the setting sun seen on the horizon has in fact already dropped below the horizon. Twinkling stars are also an effect of this same process, called refraction. Light passing through a medium such as air or water can be absorbed and scattered by the
hollow pipes or transparent rods to transmit images for television or fascimile systems. Heinrich Lamm was the first person to demonstrate image transmission through a bundle of optical fibers. Holger Moeller applied for a Danish patent on fiber-optic imaging, but was denied based on other research Abraham Van Heel and Harold H. Hopkins presented imaging bundles in the British Journal Nature at separate times.Van Heel later produced a cladded fiber system that greatly reduced signal interference
biological, environment and medicine fields [7-16]. Fiber optic SPR sensor has various advantages compared to conventional prism-based SPR sensor such as miniaturization, simplified optical design, remote sensing, high sensitivity due to SPR as well as real-time analysis and online detection [17]. Due to the structural particularity of optical fiber, propagation of light beam within it is very complex. Depend on the past experiences on fiber optic sensor, it was difficult to obtain high reliability and
to fiber optic technology. In 1979, AT&T filled the telecommunications industry with revolutionary ideas by developing a mode for data transmission using a light, called fiber optic cable. This mode produced a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits on one fiber alone (Cole, M. 2000). However, this development was merely the start of a huge extension to telecommunications, something that would transform the industry constantly. Although AT&T brought in fiber optic technology
Photonics / Optics Specialist Often overlooked, light plays a big factor in everyday life; it is the key to survival. Light is used for everything from cellular respiration to the lasers in DVD players. Photonics and optics both involve the study of light. Photonics is the study of how light can be used to transfer information. Meanwhile, optics focuses mainly on the way light affects and is affected by other things. An optics or photonics specialist is the name given to someone who has expertise
Hasan Ibn Al Haytham: the optics scholar In Islamic Golden Age, the time where the Islamic civilization advanced, during this period, Engineers, Scientists, and Merchants of the Islamic world contributed significantly to different fields such as Art, Agriculture, Economy, Literature, Navigation, Philosophy, Science, Technology, and Astronomy. At that time born a brilliant child in 965 AD, south of Iraq, Basra called Abu Ali Muhammad Al-Hasan Ibn Al-Hasan Ibn Al-Haytham, known as Hasan Ibn Haytham
An Introduction to Fiber Optics Technology Throughout time, speed and efficiency in the telecommunications industry has progressed at a rapid pace due to fiber optic technology. In 1979, AT&T revolutionized the telecommunications industry by producing a medium for data transmission which used light, called fiber optic cable. This medium created a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits onto one fiber (Cole, 2000). However, this invention was only the beginning of a great
Technology There are four methods of data transmission on Internet: DSL, cable, wireless (wireless), and fiber optics. DSL is an existing copper wire of a phone line to deliver high speed internet access. Cable is to utilize a coaxial cable that connects to a television set. WIFI represents wireless that are used for Internet connection without wire. Fiber optic offers many advantages over conventional copper cable lines. It is able to transmit data much faster over greater distances and because
Optics of the Eye The component of the eye is optically same as the usual photographic camera. It has a cornea, pupil, lens and retina. (1) Cornea The cornea of the eye is transparent, curved that acts as the cap of the eye which protects the eye from dirt, microorganisms and other harmful substances.(2) It is also important for about 75% of the eyesight. Its clarity and the curvature will affects the eye by how greatly it can focus on an object and produce an image. However, 10% of the incident
Like a lot inventions in the past two centuries, modern fibre optic cable was created for military uses. The manager for Copper Cable and Wire at the US Army Signal Corps was getting more displeased with the amount of signal loss that was due to copper cable. Like any person high of rank in the Army, he decided to take his trouble out on someone lower then him. In this case it was a man named Sam DiVita. DiVita wanted to use light transmitted via glass fibre to send signals from point to point
Robert Bunsen and Niels Bohr. The discovery of Fraunhofer lines was based on earlier work in the field of optics, and lead to many discoveries in astronomy, chemistry, and physics. In 1604, Johannes Kepler published the book Astronomiae Pars Optica. The book has been considered by many to be the basis of all modern optics. In his research, Kepler discovered many of the fundamental principles of optics (Molecular Expressions). He discovered how the eye bends light in order to form an image. He was one

At the University, he studied both physics and medical physiology. There, his doctoral teacher was Andreas von Ettingshausen. Mach received his doctorate in physics in the year 1860. Earlier his work was composed of working on the Doppler Effect in optics. After receiving his doctorate, Mach went on to teach mathematics as a professor at the University of Graz. He was a doctoral advisor to Heinrich Gomperz, another austrian physicist. Although he was teaching mathematics, his interests were still with
important contributions to many fields of science. His discoveries and theories laid the foundation for much of the progress in science. Newton was one of the inventors of a mathematics called calculus. He also solved the mysteries of light and optics, formulated the three laws of motion, and derived from them the law of universal gravitation. Newton was born on December 25, 1642, at Woolsthorpe, near Grantham in Lincolnshire. When he was three years old, he was put in care of his Grandmother
2.6.2.2 Waveguide Dispersion The effective index varies with wavelength not only due to of material dispersion, but also because varies with . In turn, it varies with wavelengths. These implicit variations of [ ] with gives rise to the second cause for chromatic dispersion, which is term waveguide dispersive [D37]. The total dispersive are combinations of the relative contributions of waveguide dispersion and material dispersion for a conventional single-mode fibers. The zero-dispersive
at the age of 75 in Syracuse. It is said that he was killed by a Roman soldier, who was offended by Achimedes, while the Romans seized Syracuse. Archimedes had a wide variety of interests, which included encompassing statics, hydrostatics, optics, astronomy, engineering, geometry, and arithmetic. Archimedes had more stories passed down through history about his clever inventions than his mathematical theorems. This is believed to be so because the average mind of that period would have
