Abstract
A system for detecting trace-gas includes an optical sensor mounted on a vehicle and processing circuitry. The optical sensor includes a plurality of interferometers configured to collect samples. The processing circuitry is configured to generate a digitized signal based on the samples, apply a forward Fourier-transform on the digitized signal to generate spectrum information for the plurality of interferometers, and determine a gas species has been detected using one or more intensity of absorption features of the spectrum information corresponding to the gas species from the spectrum information.
