Intrinsic sensors use the optical fiber itself as the sensing element, where the measurand directly affects the light traveling through the fiber. These are highly sensitive and suitable for strain, temperature, and pressure measurements in structural health monitoring or aerospace applications . Extrinsic sensors rely on an external transducer, with the fiber transmitting light to and from the sensing element. They are ideal for remote or hazardous locations, such as inside jet engines or high-voltage transformers, where electrical sensors are impractical . Hybrid sensors combine intrinsic and extrinsic features, offering flexibility for complex measurement environments .
Fiber Bragg Grating (FBG) sensors are widely regarded as high-performance fiber optic sensors. They detect strain, temperature, and pressure by measuring shifts in the reflected wavelength of light within the fiber. FBG sensors provide high resolution, can be multiplexed along a single fiber, and are extensively used in structural monitoring, aerospace, and energy sectors . Intensity-based sensors are simpler, detecting changes in light intensity caused by obstruction or modulation. They are cost-effective and suitable for object detection or industrial automation . Interferometric sensors measure phase changes in light, offering extremely high precision for detecting minute displacements, vibrations, or deformations . Polarization-based sensors detect changes in light polarization, useful for measuring magnetic fields or currents affecting the fiber .
