A light-collecting fiber optic sensor consists of a light source, optical fiber, sensing element or transducer, and a detector. The optical fiber serves as a conduit for light, either carrying it to the sensing region or collecting light reflected or emitted from the target. The transducer modulates a property of the light—such as intensity, wavelength, phase, or polarization—based on the measurand, which is the physical quantity being measured. The detector then interprets these changes to quantify the parameter of interest .
Light-collecting fibers are designed to maximize the capture of light from the sensing region. This can involve:
Fiber optic sensors offer high sensitivity, immunity to electromagnetic interference, remote sensing capability, and suitability for harsh environments. They are widely used in structural health monitoring, biomedical sensing, chemical detection, and industrial process control . In summary, the principle of light-collecting fiber optic sensors relies on guiding light through optical fibers and detecting changes in its properties caused by external stimuli, with the fiber either acting as the sensing element itself or as a conduit to an external transducer. This enables precise, non-contact, and remote measurement of a wide range of parameters.
