Lasers And Fiber Optics

Optics fiber cables do not stop amazing us for the many uses that are found for them everyday. They are the product of the wonderful blend of art and science. Made form an array of thin glass and plastic, a fiber optic cable has one side that is a light source and another one that is a camera lens.

We can call the last decade as the fiber laser optics era. Almost all the devices that form part of our daily life rely of fiber optics technology. Our cell phones, pagers, fax machines and out Internet connexions are the final results of large research on fiber optics, laser and the quantum mechanics of Einstein. He came up with the principle of stimulated emission, which means that electrons could absorb and emit energy of photons at a single frequency. Later on, this was developed to create the microwave emission, and then, this was applied to visible light and finally landed on laser.

The use of lasers in fiber optics is an important milestone in the technical field. Because of their capability for higher modulation frequency, lasers were identified as an important means of carrying information. Laser diodes (LD) or light emitting diodes (LED) have the power to create tremendous amount of light that is very useful for fiber optics. In the earlier days there were only ruby lasers and helium-neon lasers. Then semiconductor lasers made their entry. Today fiber optics technology employs these semiconductor lasers. Lasers help fiber optic technology in data communications, sensing and other applications.

Optic fibers are used widely in the medical field for diagnosing and treating a variety of ailments. Because optic fibers can be made extremely thin and made into flexible strands, they can be used for insertion into blood vessels, lungs and other parts of the body. Optic fibers have been enabling physicians to look and work inside the body through tiny incisions with an instrument called an Endoscope. An Endoscope is a medical instrument made to carry two bundles of optic fibers inside one long tube. One bundle of optic fiber directs light at the tissue being examined, while the other bundle of optic fiber transmits light reflected from the tissue, producing a detailed image. Endoscopes may be designed to look into specific areas of the human body. For example, physicians can use the optic fibers in the Endoscope to examine knees, shoulders and other joints in the body.

Although fiber optics training is advertised by many institutions, only some conform to international standards. Fiber optics training involves a comprehensive, integrated teaching program that meets the requirements of designers, installers and consumers of fiber optic products.

Enter the Dragon You stumble through a maze of mirrors, placed methodically so that the camera filming you doesn’t film itself… you have hot pink fluids smeared over your arms and torso as an obscure, esoteric reference to human blood… there is a chinese actor chasing you with an over-sized rabbit’s foot with marshmallow roasters attached to the fingers as an obscure esoteric reference to a bear-claw-esque weapon (which will henceforth be reverenced in the form of a mouth-watering innamon/frosting medley pastry).
