Fiber optic sensor

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 fastest growing field in the past years. There has been a vast development in the fiber optic sensor technology since the first sensor was patient 40 years back in USA during mid 1960’s named as Fotonic sensor. This can be traced back to papers presented…

considering the demerits of optical fiber networks. Despite of the fact that the cost for fiber is dropping by 60% per year and is beneficial in long run, its initial installation cost is still high and is not affordable to all vendors. Per unit cost of fiber cable is more than that of copper cable. Secondly, as the technology is still new and improvising, it requires skilled manpower for its installation, operation and maintenance. Further it requires new equipment compared to prevalent…

The limitations of copper and coaxial cable cannot keep up with the ever-increasing demands of distance, bandwidth, and real estate. The potential bandwidth of fiber has not been fully utilized and it is already transmitting signals at multiple gigabits per second. Fiber optic cables can go an average of 62 miles versus 1.2 miles that copper can go before the signal needs to be regenerated or boosted. Overall, it is apparent that fiber optics is a more cost effective solution. Fiber optics is…

of optical fiber sensor in biomedical Optical fiber sensor for biomedical application Applications for biomedical sensors can be named in vivo or in vitro. In vivo alludes to application on an entire, living life form, for example, a human patient; in vitro alludes to testing outside the body, for example, research facility blood tests. From the point of view of how sensors are connected to a patient or organic framework, they can be named noninvasive, reaching (skin surface), negligibly…

Design of the modified optical sensor used with Equations 1 and 21. The power to integrate an optic fiber into fabrics was measured to determine whether the optic fibers broke during the integration process. Equation 3 was used for the power calculation in decibel-milliwatts (dBm) 1. dBm=10 log(P_transmitted/(1 mW)) [3] Integration of the fibers into fabric has been successful. The diameter of the fiber that has been developed is 1 millimeter thick. One challenge is to minimize the size…

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…

environmental sensors, this group consists of sensory devices for assessment of the surrounding including but not limited to temperature, pressure, humidity, wind and rain and even corrosion. 2. traffic monitoring sensors, this group consists of sensory devices for assessment of the traffic load on the bridge using dynamic motion stations, traffic cameras and dynamic strain gauges. 3. bridge monitoring sensors, this group consists of sensory devices for assessment of the bridges characteristics…

using light (Mercer, 2017) It functions by using common Light Emitting Diodes (LED) to facilitate data transfer at speeds up to 224 gigabits per second (Mercer, 2017). Li-Fi proposes a world where common sources of light are able to connect us to the internet. The term Li-Fi was invented by Harold Haas, a University of Edinburgh Professor in 2011. He foresees light bulbs acting as wireless routers and later went on to set up a company, pureLiFi with the goal of becoming an authority in VLC…

Using this approach, we will confine P. aeruginosa bacteria tagged with mCherry, a fluorescent-protein-based reported, within 3D microstructures on the optical fiber tip. We will then expose the bacterial structure with an excitation source to create excited states promoting fluorescence, which we will detect using a photomultiplier tube (PMT). The fluorescence is an expression of mCherry, which gets activated when cells respond to several environmental factors like QS signals or oxygen levels…

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…
