“…The primary advantage of BOTDR technology is that only one end of the fiber needs to be accessible. Both these types of Brillouin fiber sensors were employed successfully due to their accuracy in measurement of various measurands like strain and temperature [118], for monitoring of various structures, components and parameters like pipeline buckling [119], pipeline corrosion [120], power transmission lines [121], crack detection by separate measurement of strain and temperature [122] and their simultaneous measurements [123]. In general the classifications and types of fiber optic sensors are purely authors and manufacturer specific but for end users they are sensors which probably act as control system i.e FOS system should sense and activate/trigger warning.…”

The last couple of decades had witnessed a steep rise in extensive research of optoelectronic and fiber optical communication fields, which resulted in applications focused initially in military, aerospace equipments, and later in health monitoring for medicine, heritage culture and various engineering fields. Health monitoring has attracted the effort of many engineers throughout the world and is fast emerging as a pioneering field. It is helping to improve world economy in two ways; first, directly by providing longevity to all the important structures and secondly, by prevention of untimely failure leading to loss of life and money. This field is very vast, consisting of traditional monitoring methods as well as smart system based methods. The fiber optics belong to finest class of smart materials, there are many types and classifications of fiber optics based on necessity, manufacturer and the end user. This paper, gives a complete over view of fiber sensing systems and their usefulness. In addition, it highlights some of the general fiber optics available in the market with selected examples.

“…), fiber-optic temperature sensors have many inherent advantages such as immunity to electromagnetic interference noise and capability of (quasi-)distributed measurement. In particular, distributed temperature sensors based on Brillouin scattering in optical fibers have gained a great deal of attention for the past several decades because of their truly distributed measurement capability with high stability [1,2,3,4,5,6,7,8]. In conventional fiber-optic Brillouin temperature sensors, their sensing heads comprise glass optical fibers such as silica single-mode fibers (SMFs) [1,2,3,4,5,6], tellurite glass fibers [7], and photonic crystal fibers [8], which are so fragile that they cannot withstand strains of over several percent.…”

Poly(pentafluorostyrene) (PPFS), which can be easily synthesized and has a low optical loss window at 850 nm, is a promising alternative for a costly perfluorinated polymer as a base material of polymer optical fibers (POFs). To investigate the potential of a PPFS-POF as a Brillouin-based temperature sensing fiber, the Brillouin frequency shift and its temperature dependence of PPFS were measured using an ultrasonic pulse-echo technique. The temperature coefficient, which determines the sensitivity of the temperature sensing, was approximately !7.1 MHz/K independently of the molecular weight and was nearly identical to that in perfluorinated POFs.
