摘要： Interferometric equipment for detecting a substance having a structure preferably a periodic or quasiperiodic absorption spectrum; the equipment includes a source of radiation, a path for that radiation that includes a sample cell with the substance to be detected, an interference filter and a detector, and is improved in that the interference filter is constructed as an electrically tunable filter, including a plate or cell element with semitransparent reflective boundaries serving as electrodes; an electrical voltage is applied to said electrodes such that the transmission characteristics of the filter is varied and the amplitude of the voltage as applied to these electrodes is an indication of that variation; and the thickness of the plate or cell is selected to meet one of the following criteria (i) a distance between the interference lines produced equals a distance of absorption lines within a periodic absorption spectrum of said substance; (ii) the equipment causes a line to be separated from the radiation having a bandwidth which is small as compared with a spacing between two absorption lines of the substance to be found (iii) the equipment causes a line to be separated from the radiation, to overlap an edge of an absorption band of the substance to be directed.

摘要： An interferometric analyzer for the detection of substances having a structured absorption spectrum such as a periodic or quasiperiodic absorption line pattern, within a gas blend, and comprising a source of radiation for directing radiation into a radiation path that includes a container, cell or the like which contains the substances to be detected, the path includes further a filter system, which includes an electrically or temperature controlled Fabry Perot element such that the spacing between the transmission lines of the interference corresponds to spacing of absorption lines of different substances for different absorption bands of these substances; and a dispersion filter each circularly variable or another Fabry Perot filter is positioned in the radiation path for selecting a respective spectral region as far as a particular substance is concerned by means of the controlled disperging element.
