Reflectivity refers to the proportion of light that is reflected back from a target or internal sensor interface to the receiving element of a fiber optic sensor. In reflective fiber optic sensors, light emitted from the sensor head strikes a target and returns to the receiver, with the sensor detecting changes in the intensity of the reflected light to determine the presence, position, or properties of the target . High reflectivity ensures a stronger return signal, which improves the sensor's ability to detect small or distant targets and reduces susceptibility to noise.
