Abstract
The coherence multiplexing of absorption sensors is realized based on a path-scanning Michelson interferometer (MI). The sensing units are designed with different optical path lengths, and the signals from the inline sensing array can be demultiplexed by a path-scanning MI. Intra-cavity absorbance in each unit can be deduced from the corresponding signal and the signals of the previous sensing units.
