Abstract: Methods and systems for detecting a gas or liquid in an environment include measuring a reference signal at each of a set of wavelengths by passing a signal at each wavelength through a reference cell having a gas or liquid to be detected. A sensing signal is measured at each of the plurality of wavelengths by coupling each wavelength to a ring resonator in the environment. A set of wavelengths that correspond to an absorption curve of the gas or liquid to be detected is determined. A concentration of the gas or liquid to be detected in the environment is determined based on amplitudes of the sensing signal at each of the set of wavelengths.

Abstract: A system including a light source, sampling tray, and a plurality of fiber optics positioned to achieve high contrast to improve accuracy and eliminate the need to rotate the sample. A composite light image from the fiber optics is fed to a spectrometer which converts the reflected light into a fingerprint corresponding to the concentration of at least one substance in the sample. The fingerprint is processed by a statistical model to determine concentration level of the at least one substance in the sample and the concentration level is then displayed.
