Advantages of optical fibers in optical waveguide sensors
Optical fiber sensors present several advantages in relation to other types of sensors. These advantages are essentially related to the optical fiber properties, i., small, lightweight, resistant to high temperatures and pressure, electromagnetically passive, among others. Sensing is achieved by. The usage of fiber‐optic sensors has flourished in many fields over the past 30 years due to the fiber‐optic's inherent advantages: cost‐effectiveness, miniaturized size, light weight, and immunity to electromagnetic interference. At the heart of this technology is the optical fiber itself -- a hair-thin. The dramatic reduction of transmission loss in optical fibers coupled with equally important developments in the area of light sources and detectors has brought about a phenomenal growth of the fiber optic industry during the past two decades.
