Optical Fiber Communication Course Code-MCS-616 1. Draw a diagram to approaches of optical communication. 2. Draw a block diagram of Light wave application areas. 3. Why do we use fiber computing? State the characteristics of optical fiber communication. Why we Use Optics for Computing? One of the theoretical limits on how fast a computer can function is given by Einstein’s principle that “signal cannot propagate

Rachel Hahn Cheryl Blackwell Seminar November 2012 Optical Illusions An illusion is the distorted perception of a stimulus. They are not to be confused with hallucinations‚ which are false perceptions when there is no presence of a stimulus‚ in contrast‚ illusions are the misinterpretation of a true sensation (Illusion Wikipedia). Illusions are mundane phenomena‚ and are experienced by nearly everyone in similar ways where hallucinations are a personal experience and are typically limited

[pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation

The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

ABSTRACT Title of Thesis: FREE-SPACE OPTICAL COMMUNICAITONS THROUGH A FOREST CANOPY Clinton Lee Edwards‚ Master of Science‚ 2004 Thesis Directed By: Professor Christopher C. Davis‚ Department of Electrical and Computer Engineering This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index

Optical illusions are all around us(explain). The brain remembers what it has seen before‚ then when it sees something similar it takes shortcuts when looking at a new images. This causes the brain to make mistakes and creates optical illusions. An optical illusion is a misleading image that deceives the eye. Different people see optical illusions differently because of their previous experiences. Previous experiences help the brain interpret what it sees. If your previous experiences determine

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

Assignment 9 There are two main types of 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

Anniversary Souvenir 2013 Optical Fiber Project & its Impact Background In the initial days‚ the backhaul of telecom equipments relied on microwave and satellite communication. The rapid proliferation of various telecom technologies and the desire to penetrate larger market segments resulted in high national and international traffic. The high cost of space segments for statellite communications and limited capacity of Microwave links compelled Nepal Telecom to embrace the optical fiber deployment to
