Abstract
An apparatus is provided that includes a plurality of reflectors arranged over an area, and a plurality of transceivers. A first of the transceivers is configured to transmit radiation at each of the plurality of reflectors at a first wavelength and a second wavelength, and receive radiation reflected from each of the plurality of reflectors. A second of the plurality of transceivers is configured to transmit radiation at each of the plurality of reflectors at a third wavelength and a fourth wavelength and receive radiation reflected from each of the plurality of reflectors. The apparatus includes a processor configured to calculate a change in concentration of a gas within the area between a first time and a second time based upon signals received from the transceivers.
