A DIAGNOSTIC METHOD AND A DEVICE FOR ITS IMPLEMENTATION

摘要

The present invention relates essentially to the art of experimental biology and physiology. The method involves generation of an SHF signal, splitting of the signal into a reference and measurement signals, exposure of an area of the specimen to the latter signal, and reception of the LF-frequency-modulated reflected signal. The resulting signal permits quantification of a status-indicative physical parameter of the specimen's area. To emit the signal, use is made of a circular cross section waveguide obturated by a set of dielectric discs. The phase of the measurement signal is shifted by an angle pi and that of the reference signal, by an angle pi /2, and the resulting signal is used to find the magnitude of integrated dielectric permittivity of the exposed area or the object as a whole. The device comprises an SHF oscillator, a 3 dB four-branch coupler, a measurement unit, waveguide transmission lines of the measurement and reference signals and phase modulators.
