Fiber optics is a kind of optics dealing with the movement of light through fibers or thin
rods of glass. If light is put at one end of a fiber, it can move through the fiber with
very low loss of intensity, even if the fiber is curved.

The simplest use of optical fibers is the moving of light to places hard to reach, for
example, inside a dentists drill. Also, bunches of several thousand very thin fibers put
together, can be used to view images. Each point of the image made on one side of the
bundle is made at the other end of the bundle, remaking the image, which can be observed
through a magnifying glass. Image transmission by optical fibers is used a lot in medical
instruments for looking inside the human body and for laser surgery, in copying machines,
in computer graphics, and in many other machines.

Optical fibers are also being used in sensing devices, ranging from thermometers to
gyroscopes. The fibers can be really useful where electrical effects could make ordinary
wiring useless, less accurate, or even hazardous. Fibers have also been developed to carry
high-power laser beams for cutting and drilling.

One growing use of optical fibers is in communication. Because the information-carrying
capacity of a signal increases with frequency, the use of laser light makes many
advantages. Fiber-optic laser systems are being used in communications networks. One
advantage of optical fiber systems is the long distances that can be continued before

If a target is detectable when still, it becomes even more so when it is in motion. The brain uses multiple cues to help us perceive motion including information from all of our senses. The focus of this paper will be the visual system and how motion is perceived visually. Motion is in part perceived by the changing pa
