Fiber optic sensorsFiber optics itself can be used as a sensor. This can be used to connect non ber

optic sensor to a measurement system. Fibers are used in sensing devisers because

of their small size and the fact that no electric power is needed at remote locations. They can be used to measure rain, temperature, pressure and other quantities by

modifying it so that the property that is measuring will change characteristics like

intensity, phase, polarization, wave length of light inside the ber. For example ber

can be used to take measurement inside an air craft et engine !which is hard to

reach" by transmitting heat radiation !#$" into an #$ sensor. %ince its immune with

high electromagnetic elds measurements can be taken at the places where electric

devices fail.

Fiber optic communicationFiber optics use as a medium of telecommunication and computer networking.

&ecause of its 'exibility and ability of making bundles. The most prominent

advantage is that light propagate through the ber with less attenuation compared

to electric signals and metal wires. &ecause of the capability of transmitting light

with di(erent wave lengths through the same ber the signal band which is much

higher making the data transfer speed rising up to the order of gigabit per second.

)ommunications via bers are also immune to electric interference making

communication much safer under electric storm environments.

LASER in Spectroscopy*onochromaticity and well dene range of wavelengths in a laser can be carefully

moderate to make a pure light source in the sense of length width. These can be

used to induce nonlinear optical e(ects in a sample to use with $aman

spectroscopy. They can be also use to detect molecules in the level of part per

million. +igh power density of lasers enable beam induce atomic emission to

perform laser induce break down spectroscopy

Militaryasers are sung to confuse the seeker head on a heat seeking anti air craft missiles.

+igh power lasers such as tactical high energy laser !T+-" are using to track and

destroy intercontinental ballistic missiles !#)&*". nother military use is the laser

targeting designator which is a low power laser that is used to indicate a target.

%pecially designed war heads are launched from air crafts that are adusting its

'ight path to the laser point making precise target take downs. aser sights are also

used in weapons to enhance the targeting of a weapon.
