Fiber serves as a continuous sensing element. Sensing is based on. { 1 + ln( / ) z + ln( / ) } Equipped with safety features and remote fault monitoring.
Optical fiber sensors offer attractive characteristics that make them very suitable and, in some cases, the only viable sensing solution. Some of the key attributes of fiber sensors are summarized below.
These developments paved the way to a plethora of different works on fiber optic sensing. But, what is an optical fiber sensor? Figure 1 shows a block diagram of a typical optical fiber sensor.
In this section we will briefly discuss the ways in which optical fiber Bragg grating sensors can be individually interrogated and collectively multiplexed in order to be able to perform multi-point sensing.
