Paper Abstract

Time-domain (TDM) and frequency-domain (FDM) multiplexing techniques for near-IR diode laser spectroscopy based gas sensors are described. Three multiplexing techniques are demonstrated on a passive optical fiber network with four sensors. Absorption sensitivities varying from 2.5%, for a direct detection TDM systems, to 0.01% for a frequency modulation spectroscopy FDM system, are demonstrated.
