摘要: The invention relates to a miniaturized spectrometer for gas concentration measurement. The spectrometer comprises a radiation source (3) for admitting electromagnetic radiation onto the gas to be measured, a detector (5) for detecting the radiation transmitted through or emitted from the gas, an electrically tunable Fabry-Perot interferometer (4) placed in the path of the radiation prior to the detector (5), control electronics circuitry (2) for controlling the radiation source (3), the interferometer (4) and the detector (5). According to the invention, the radiation source (3), the detector (5), the interferometer (4) and the control electronics (2) are integrated in a miniaturized fashion onto a common, planar substrate (1) and the radiation source (3) is an electrically modulatable micromechanically manufactured thermal radiation emitter.
