FIELD: measurement technology. ^ SUBSTANCE: method involves transforming oscillations and measuring signal values obtained as a result of transformation, for example, signal amplitudes and frequencies. Frequency spectrum of fluctuations is transposed and compressed by means of interferential modulation and beating detection. Signal instances, obtained by performing specified spectrum transformation, are summed. Intensity, wavelength of oscillations under study are determined by measuring resulting signal and their identification is carried out. ^ EFFECT: increased frequency range of investigated fluctuations. ^ 5 cl, 1 dwg
