Abstract
Methods and systems are provided for monitoring at least one gas in a sample gas. An exemplary system includes a source used for generating a beam of radiation, at least one retro-reflector configured to receive the beam of radiation from the source in an incident direction and reflect the beam of radiation toward the source in alignment with the incident direction, and a motor configured to move the at least one retro-reflector with respect to the source in a direction collinear with the incident direction. The system also includes a sample cell storing a sample gas comprising at least one gas. The sample cell is configured to allow at least a portion of an extracted beam of radiation from a cavity, defined by the source and the at least one retro-reflector, to propagate therethrough.
