The introduction of interference–polarization filters (IPFs) in the structure of an optical–absorption analyzer makes it possible to pick out a harmonic (a Fourier component of the absorption spectrum) providing measurement with the highest sensitivity. The selectivity of such a method of analysis is determined by overlapping the oscillations of the measured and interfering components. By the example of measurement in benzene in the presence of an interfering component (toluene), the possibility is considered for the optimization of selectivity due to the variation of the path-difference dispersion for ordinary and extraordinary interfering rays. The metrological characteristics of the interference–polarization analyzer of C6H6 confirming the results of calculations are given. © 2016, Pleiades Publishing, Ltd.

A new analytical method of optical absorption analysis, based on selection of a Fourier component of the absorption spectrum (characteristic of the material under study) by a polarization interference filter, has been proposed and tested experimentally. © 2016, Pleiades Publishing, Ltd.

A number of B.N. Grechushnikov's works were devoted to the application of interference-polarization filters as a two-beam interferometer for Fourier-spectroscopy. In this paper the potential of these filters for the optical absorption method of gas analysis (specifically, the selective measurement of components with overlapping absorption spectra) is considered. © Pleiades Publishing, Inc., 2011.

A technique for calculating absorption interference patterns of aromatic hydrocarbons with allow- ance for the birefringence dispersion of an interference-polarization filter is proposed. An experimental model of an optical absorption gas analyzer based on a Wood filter with magnesium-fluoride plates for mea- suring benzene and toluene characteristics is described. The measurement data are compared with the calcu- lation results. The possibility of applying a combined plate to improve the selectivity of absorption measure- ments for benzene with respect to toluene is considered. © Pleiades Publishing, Inc., 2013.
