Abstract:
An on-chip spectroscopic sensor includes a tunable diode laser. A laser driver for drives the tunable diode laser. An analyte test cavity receives a chemical sample and exposes the received chemical sample to light from the tunable diode laser. An optical detector detects light emerging from the analyte test cavity as a result of the laser exposure. A spectral analyzer determines a spectrum of the emerging light, matches and removes one or more known optical fringe patterns from the determined spectrum, and determines a composition or concentration of the chemical sample from the optical fringe pattern-removed spectrum.

Claim (Index 12):
A method for detecting fugitive methane gas, comprising:\n installing a spectroscopic sensor apparatus into a calibration tool; using the spectroscopic sensor apparatus within the calibration tool to identify a plurality of optical fringe patterns at regular temperature increments within a predetermined temperature range; store the plurality of optical fringe patterns within a database; configure the spectroscopic sensor apparatus by constructing a background removal model that is configured to detect one or more of the plurality of optical fringe patterns while correcting for laser frequency ramping instabilities by allowing each of the plurality of optical fringe patterns to be stretched/contracted; removing the configured spectroscopic sensor apparatus from the calibration tool; installing the configured spectroscopic sensor apparatus to a final location; and using the spectroscopic sensor apparatus installed at the final location to detect fugitive methane.
