    摘要: An optical gas measurement using a Vertical Cavity Surface-Emitting Laser (VCSEL) and a hollow waveguide connected thereto, wherein the hollow waveguide contains a gas to be measured and conducts light. To this end, the hollow waveguide is made to vibrate. The gas measurement is performed and integrated over a period of time. As a result, disturbances of the measurement caused by interferences are considerably reduced.

    摘要: A method an apparatus uses the narrow-band measurement of the absorption of given spectral lines of a gas using laser light sources, so that the spectrally resolved measurement of individual absorption lines, and thus the selection of an individual gas component, is possible. A laser diode which is operated at a higher temperature is correspondingly varied over a certain temperature region, wherein the selected spectral line is crossed. On the basis of absorption measurements, the method and sensor deliver the gas concentration, with a high selectivity.

    摘要: A method for controlling or monitoring firing systems and for monitoring buildings having gas burners using spectroscopy, provides at least one wavelength-tunable monochromatic light source. An absorption spectrum of a measuring gas is received with at least one photodetector in an absorption path with spectral tuning of the light source, and the concentration of target gases carbon monoxide (CO) and methane (CH4) can be determined simultaneously during tuning of the light source. A device for carrying out the method includes a monochromatic laser diode, in particular a VCSEL, an absorption path in the exhaust gas region or a space endangered by leakage, a photodetector for receiving light passed through the absorption path, and an evaluation unit for determining the concentration of target gases based on the absorption spectrum covered during the laser or laser diode tuning. The method and device are applied in laser-optical gas sensors in gas firing systems.
