Abstract: A novel scheme for enhancing the multiplexing capacity of low-coherence reflectometric sensors is demonstrated. The scheme is based on connecting the sensing elements in serial in a loop configuration, allowing each of the sensors within the array being interrogated twice from opposite directions. The bi-directional interrogation doubles the multiplexing capacity while maintains the signal to noise ratio. The double interrogation scheme would allow the normal operation of the sensor array even when one end of the transmission fiber were broken, improving the reliability of the sensing system for large-scale structural monitoring.
