What is fiber opticsused for

Fiber optics is a way of sending information through thin fibers, or threads. The information may be sound, pictures, or computer codes. This information travels through the fibers in the form of light.

The cladding keeps the light moving through the fiber. Light will move in a straight line easily, but it will not turn a corner without help. As the light moves at a high speed through the core, it bounces off the cladding. If the fiber has a bend in it, the light can bounce off the cladding and turn the corner to follow the bend. The cladding also keeps the light from losing its strength. The light can travel quickly over long distances. At the end of the fibers, a machine called a receiver accepts the light. The receiver turns the light back into sound, pictures, or computer codes.

Uses of optical fibre Physics

Magnifying glasses are frequently used for reading small letters or observing small objects with a moderate amount of magnification.

The fibers, known as optical fibers, can be made of glass or plastic. They are about as big around as a human hair. Many fibers are bundled together to form a fiber-optic cable. Fiber-optic cables link some telephones and computers. Doctors also use fiber-optic instruments to see inside the human body.

What is fiber opticsmade of

In a fiber-optic system, a machine called a transmitter turns information into light. Then the transmitter sends the light through optical fibers. The inner part of each fiber is called the core. A reflective material surrounds the core. This material is known as cladding.

Most telephone cables used to be made of copper wires. Fiber-optic cables are better than old-fashioned copper wires in many ways. Fiber-optic cables are small and light. They can carry a lot of information with little interference. Fiber-optic cables are also less likely to catch fire than copper wires. However, fiber-optic cables are expensive. They also break more easily than copper wires.

MTF is a measurement of the optical performance of a lens. More specifically, MTF shows the ability of a lens to resolve detail and transmit contrast.
