QUASI-OPTICAL MULTILAYERED INTERFEROMETER FOR GASOLINE TESTING

Results of an experimental study and a calculation of the quasi-optica l multilayered structure formed by an adjustable dielectric interferom eter and a liquid investigated filling its gabs are presented. It is s hown that this structure may be used for quality tests of liquid petro leum products, for measurement and investigation of physical parameter s of liquid media in the millimeter wavelengths region. This structure is realized practically in the form of uncomplicated adjustable quazi -optical quvette filled with liquid and connected with beam-guiding el ements. Comparison of experimental data with theoretical calculations gives us the opportunity to choose a value region of the values for th e physical parameters interesting for us for each material under inves tigation.
