Abstract
Techniques are generally described related to a method and system for monitoring gas concentrations. One example gas monitoring apparatus includes a light source, a MEMS micro-mirror arranged to be in an optical path of a light from the light source that has passed through a sample and configured to direct selected wavelengths of the light to a single detection point, a detector arranged at the single detection point and configured to convert incident light into electrical signals, and a processor programmed to determine a gas concentration of one or more gases in the sample based on the electrical signals.
