Fiber optic sensor

generated based on the nonlinear propagation of the multi-cycle laser pulses, carried at central wavelength ~790nm, and τFWHM pulse duration is ~ 22 fs (in intensity) at 1mJ., in a gas filled hollow core fiber (HCF). Hence, these pulses are focused by a bi-convex lens (f=1.8 m) into the hollow core fiber entrance. The beam size at the focus is ~ 200 µm. The converging beam enters the HCF apparatus chamber, which is schematically illustrated in Figure 3a, through a ~0.5mm fused silica…

is only natural that the great thinkers of antiquity were curious about the nature of vision, and inseparably, that of light itself. In the manner characteristic of ancient science, many common ideas about optics were “hit or miss”, so to speak. Certain Greek thinkers had hypotheses about optics which are more or less in line with modern principles, but many held firmly to ideas which are at odds with the current understanding of reality. I discuss extramission theory (a hallmark of Greek…

Introduction A lens is an object that forms images by refracting light. The images formed can be magnified, real and virtual depending on what lens used and the set-up of the lens system. There are two types of lenses, converging and diverging lenses. Converging lenses cause parallel light rays to converge to a point. Diverging lenses cause parallel light rays to diverge. Typically converging lens are thicker in the middle and diverging lenses are thinner in the middle. Lenses are used for many…

I. Introduction A. On an adventure to Milwaukee any tourist would go to the Milwaukee County Zoo. The first stop is always the penguin habitat. B. Have you ever paid attention to what species it is or where they came from? C. When we see penguins it is always in the zoo or part of an animation production. Here are 3 ways to analyze penguins from what is shown on the big screen to the natural habitat. II. When I think of penguins I think of penguins of Madagascar or the Pittsburg penguins. III.…

communication systems must be based upon a wired foundation. This wired system is where fiber optics come in. Fiber…

What is Fiber Optic Cables? Back in the day we used copper wires for our tele-communication and to interconnect throughout the world. However as technology and machines start to grow more powerful, we are forced to put a change in this production of copper wires. The wire density becomes a very critical factor in the modern era, however the limit in size must always result in better performance. Fiber optics proves to be highly effective in its high bandwidth, as it allows on a single fiber to…

Optical Fibres By Jaydan Fibre optics are wires made of pure strands of glass or plastic spliced together (weaved together). These wires are as thin as strands of hair so their can be millions of them in a fibre optic cable. The wires are in bundles called optical cables and are used to transmit digital information over long distances. Fibre optics can be used for telecommunication, networking, decorations, endoscopy and much more because they are flexible, carry much more information than…

cable, Wi-Fi and fiber optic as our media. Ethernet Technology The Ethernet technology was mostly used in the LAN because; 1. We used Ethernet speed of 10mbps for areas in the LAN that required higher bandwidth 2. Our campus network model supports dual links between each distribution layer routers and case switches. We are there able to load balance the aggregate traffic from multiple access switches across the links. 3. Giganet Ethernet will be used between switches but Fiber will be used…

Coursework 1- Carbon Fibre composites compared to traditional metallic properties Introduction Carbon fibre is a material made up of thin strips of crystalline filaments of carbon woven together to create a cloth or combined with a resin or ceramics to strengthen the material. Carbon fibre is now overtaking traditional metals in where it is being used and the reasons why will be discussed further on in the report (Happian-Smith 2001: 1). Carbon fibre composites have become the leading material…

invented for monitoring health condition of an individual. This is fitted in the body of a person Wire Sensor Network or WSN is possible due improvement of sensor technology as well as computer miniaturization. As the data related to patients are stored in a WBAN it is imperative that security of the data must be maintained. Body Area Network is a system comprising of wireless network of sensors to monitor health designed for delivering personalized health-care. Acquiring communications inside…
