Fiber Sensors almost always use LEDs as the light source. The light emitted from LEDs oscillates in the vertical and horizontal directions and is referred to as unpolarized light. There are optical filters that constrain the oscillations of unpolarized light to just one. Optical fibers are also attractive for applications in sensing, control and instrumentation. In these areas, optical fibers have made a significant. For these applications fibers are made more susceptible and sensitive to the same external mechanisms against which fibers were made to be immune for. This article explores the different types of Fiber Optic Sensors, their working principles, and various applications. We'll delve into Intrinsic, Extrinsic, and Hybrid fiber optic sensors, explaining how they function.
