Home / Experiment with a Fiber Optic Sensor for Reflection Displacement
In this study, we propose a novel type of optical fiber measurement method based on a reflective grating panel for lateral displacement. The signal subdivision model with the tangent and cotangent functions is given, and error analysis and processing are studied. Fiber optic sensors (FOS) have attracted much attention of researchers over the past few decades due to some innovative characteristics, such as high bandwidth, low loss, and can work under harsh environmental conditions compared to traditional sensors. Photonic sensors offer performance and cost advantages that enable many new applications to become possible. Retro reflective fiber optic displacement sensor consists of parallel fibers with a reflector at a distance.
