摘要： The correlational gas analyzer comprises a light source passed through the gas under study, which features a quasiperiodic pattern of the specified spectral band, and an optical system with sequentially positioned along the optical path condensor, input slit iris, dispersing means to decomposed the specified spectral band of the gas under study, and rotatably mounted output slit iris configures as a disc with a plurality of slits, uniformly distributed along its circumference and equidistant from the disc center. The spacing between the centers of adjacent slits is approximately equal to the scan length of the specified spectral band of the gas under study. The output slit iris scans the specified spectral band of the gas under study across a photoreceiver, the output signal whereof drives two electric signal amplifiers. One of the amplifiers is designed as a tuned amplifier, with the resonant frequency thereof defined by a preset relation between the disc rotation speed, the number of maxima or minima in the specified spectral band, and the number of slits in the disc.

摘要： A correlational gas analyzer, comprising a light source with the light beam passed through the gas under study with a quasiperiodic pattern of the spectral band, and an optical system with sequentially positioned along the light beam condensor, input slit iris, beam dispering element and rotatably mounted output slit iris configured as a disc with a slit shaped as an Archimedes spiral. The Archimedes spiral center is coincident with the disc center and its pitch is approximately equal to the scan length of the specified spectral band of the gas under study. The output slit iris scans the specified spectral band of the gas under study across a photoreceiver, the outputs whereof drive the inputs of a first and second electric signal amplifier, with the outputs thereof connected to connected in series corrector unit and recorder. The first amplifier is a tuned amplifier with resonant frequency defined by the speed of disc rotation and by the number of maxima or minima in the specified spectral band of the gas under study.
