Abstract
A gas concentration-measuring device makes it possible to measure gas components in a gas sample. An interferometer, based on a dual-band Fabry-Perot interferometer (), is provided with a transmission spectrum that can be set by a control voltage (). The control voltage () of the dual-band Fabry-Perot interferometer () is synchronized over the course of time with the activation and deactivation of the radiation sources ().
