This paper presents an original optical method for studying the specifications of frozen soil samples. The method for determination of the moisture quantitative composition in the frozen geological rocks is based on the measurement principles for the typical spectra of attenuated total reflection (ATR) using a dual-frequency modulation method for recording the optical signal emitted by the InGaAsSb-based semiconductor heterostructures. Further development of this method will make it possible to identify correlations between the reflected radiation parameters and specifications of the electrical and acoustic properties of frozen soils during the defrosting cycle.
