Time-division-multiplexed interferometric demodulation technique with 5-million-samples-per-second capability

This paper describes a digital approach to interferometric demodulation having capabilities of high sample rates and low self noise. Using this approach, a single demodulator can be used to demodulate many interferometric sensors where data is presented to the demodulator in a time domain multiplexed format. This paper presents the basic demodulation algorithm, theoretical performance predictions, and experimental data.
