Topic: Fiber Optic Sensors
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…
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…
The Passive Optical Networks (PON) is the network which is most popular in fiber network access systems. The abstract states the actual concept of Passive optical Network it's importance. It also implies the Definition and explanation of ONT(Optical Network Terminal), ONU, FTTH-BPON and FTTH-GEPON systems in FTTx premises.
The key objectives of the lab are :
• Learning Fiber to the home - BPON and Fiber to the home - GEPON systems.
• To process the layer 2…
Design and Simulation of Microcantilevers for Sensing Applications
MEMS is the integration of active and passive elements on a single chip, which combine electronics, electrical as well as mechanical elements to use in sensing and actuation. MEMS technology used in sensing applications with use of basic mechanical elements such as microcantilevers, beams, diaphragms, springs, gears and so on. In this research paper, microcantilevers are used as basic elements for design of Sensors.…
This mechanism implemented with two sesnors which can detect a surface under the robot and move the robot accordingly. If the edge is detected on a platform by right sensor the robot will turn to its left and vice versa.
When the robot detects the edge on both the sides it moves backward untill it doesn’t detect any edge and then moves to the right side a little and repeats the above process.
Line following robot :
Now, lets design a line following robot, for that, I need to pick a 50 ext block…
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…
environment (citation). Both the chemicals sorbing onto the plastic and leaching from it are possible endocrine disruptors and are carcinogenic.

Spinning of Nylon Fiber:
The turning of the nylon filaments is completed with dissolve turning. There are two strategies for liquefy turning:
1. Grid turning
2. Extruder turning.
Lattice turning is utilized for the generation of better fibers. The nylon chips are made to fall on a hot matrix that melts the nylon pieces. The liquid nylon is pumped through a sand channel to the spinneret. The sort of fiber created relies on the quantity of gaps on the spinneret, the size and the state of the…
Characteristics of the Four Elements
The four Elements possess unique characteristics and their functions are related to these characteristics. These characteristics have been explained carefully, with ultimate simplicity; where accurate and deep meanings have been considered which will also been elaborated in future sections.
Briefly, the four Elements include the following components:
a) Fire: comes with Heat and Dryness. It is the lightest of all Elements
b) Air: comes…
