Total Internal Reflection Demo: Optical Fibers

Рет қаралды 1,447,629

8 жыл бұрын

This is a demonstration of total internal reflection in various types of optical fibers.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

@robertjandegraaf5557 3 жыл бұрын

Important to know: for (digital) data transportation, the thinner the cable, the more data can be transported. This is due to the spread of the signal since parts of the beam are reflected at different locations, which have a different path-length over the total cable length.

@physicsdemos 5 жыл бұрын

Yes, the surface needs to be smooth so that the reflection will be specular instead of diffuse. But you don't need a reflective surface, like a mirror. All you need is to have the light ray inside a solid transparent cylinder, and total internal reflection will do the rest. For more information, see kzfaq.info/get/bejne/nbGRda99z9eRYn0.html.

Does the type of light matter? For example, would a laser work? If not, why not? Colored light? What sets the signal rate and strength? That is, what device and/or process sets and/or creates the signal sent into the fiber? A form of digital pulsation of light? And, what material or materials can the cable be made of? What is most used? Plastic, nylon, flexible Plexiglas, Digital acrylic, Polycarbonate, polypropylene,etc?
