Quadrature channels generation using two unmodulated DFB lasers for passive demodulation of multiplexed interferometric sensors

A novel passive demodulation approach of relatively long multiplexed interferometers based on two-channel correlation reflectometer is proposed. Quadrature channels generation and demultiplexing of interferometers is achieved using DFB diode lasers and correlation post-processing of signals.
