Optical Fibers

What is an Optical Fiber

An optical fiber is a flexible, transparent fiber made of high quality extruded glass.

John Tyndall wrote about the property of total internal reflection in 1870.

“When light passes from one media to another it bends”

History

It consists of thousands of strands offine quality glass or quartzrefractive index about 1.7thickness about 10-6

coating with lower refractive index (1.5)

material

When light is incident at one end the ray of light undergoes total internal reflection.

Each fibre acts as a pipe and such a bundle of fibers can be used to convey images along paths of any shape it is pointed.

Types of fibers

Multi mode fibers

Single mode fibers

Applications of optical fibers

Communication

Medical sciences

Decorative items

ConclusionFiber optics can be used in both good and bad ways

Using technology in a proper way gives us best results.
