Abstract
Beside advantages; recent advances, and cost reductions
has stimulated interest in fiber optical sensing. So,
researchers combined the product outgrowths of fiber optic
telecommunications with optoelectronic devices to emerge
fiber optic sensors. Numerous researches have been
conducted in past decades using fiber optic sensors with
different techniques. Intensity, phase, and wavelength
based fiber optic sensors are the most widely used sensor
types. In this paper, an overview of fiber optic sensors and
their applications are presented.
