LAMBERTIAN GAS CAVITIES ILLUMINATED BY MID-INFRARED LIGHT-EMITTING DIODES

摘要

The present disclosure describes a Lambertian gas-sensing system that may enable gas sensing in a compact form factor. The Lambertian gas-sensing system may include a hollow cavity, one or more light-emitting diode (LED) illuminators, one or more light- absorption detectors, and a gas exchange manifold. The hollow cavity may mechanically integrate the gas exchange manifold, the one or more LED illuminators, and one or more light-absorption detectors (such as one or more optical detectors). The gas exchange manifold may introduce gas into the hollow cavity and the one or more LED illuminators may emit light into the hollow cavity through one or more ports. The one or more light- absorption detectors may receive light from the hollow cavity through one or more ports.
