ECE-669c INDEPENDENT SUDY ON FIBER OPTIC SENSORS Mr. Prasanna M.Thawale School of Computer science and Engineering, California State University Northridge, Northridge-91324. Independent Study On Fiber Optic Sensors  Overview: Term: Fall-2014 Guide: Prof. Nagwa Bekir Topic: Fiber Optic Sensors .  Introduction: Fiber optic sensor since their emergence have been a sector of keen interest for researchers because of their specific and exclusive characteristics thus resulting into the…

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

2.) A: Although life is often filled with chaos and unpredictable futures, I do agree with the author Steven Johnson. I believe that as unpredictable this world is, that we must do our very best to predict to the best of our ability the effects each new innovation may bring. I would never have recognized some of these connections that have been made in this book between two things that could be so different. My favorite one being the air conditioning. The push for the invention of the air…

Many optical illusions take advantage of our perception, being a "construction project" and our brain constantly trying to estimate the best guess, leading for us to be easily tricked. The moon illusion is an optical illusion which causes the moon to appear larger near the horizon than it does higher up in the sky. One of the most famous illusion and most widely discussed has been the so called "Moon Illusion". For many years psychologists have known about this and have proposed many theories to…

Optical fiber thin as hair is everywhere on this planet, carries an enormous amount of information from place to place. There are a number of desirable characteristics of the optical fiber for conveying this information. They have the ability to carry large amounts of information, a low cost and have the immunity from electrical wiring and wireless communication link a number of disturbances that can afflict. Advantages of optical fibers for transmitting information from place to place, it…

for mobile network, however optical network is required for the communication of large amount of data in short period of time. Many smarter devices are being added to network to fulfil consumer’s demand. There are many complications and strains have arisen to optical networking with the advancement of technology. some management and security techniques can be adopted to get the best out of network infrastructure. More security and control mechanisms are added into optical networks for the…

In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal…

Moon Illusion: A Continued study of Existing Hypothesis Xinran Wei PSYC 182 Reading Group 12 Moon Illusion: A Continued study of Existing Hypothesis One of the most extraordinary optical illusions in nature, the moon illusion has attracted attention from generations of scientists. It seemed that despite of the distance between earth and moon did not change, the size of the moon appeared larger in the horizon but smaller at zenith. The debate of explanation behind this illusion…

dispersion, intramodal dispersion, bandwidth limitation, polarization mode dispersion, optical cross talk, and attenuation issues. Finally, this paper will end with a mention of current research and future research in the field and then a brief…

The temperature outside was 73 degrees, but fuses were blowing at Tuesday’s City Council meeting. Continuing business from October’s meeting, councilmember Dale Reynolds requested that a special meeting be held in the interest of homelessness in the city. Having that meeting in the Multi-purpose Room with department heads from city agencies, two council members met on Wednesday to put their heads together to implement a way, to solve the ever growing problem. “Homeless people, whether they…
