Способ используется для исследования и анализа материалов с помощью электромагнитного излучения. Сущность изобретения: источник излучения вырабатывает сигнал частоты wо, которая выбирается в диапазоне значимой второй производной показателя преломления искомого компонента и в случае удаленности от этого диапазона подстраивается к нему посредством блока. С помощью модулятора несущую частоту ωo модулируют с частотой Ω , которую вырабатывает генератор. Модулирование осуществляют по амплитуде или фазе по определенному ( например, гармоническому ) закону. В принимаемом излучении регистрируют изменения во времени соответственно фазы или амплитуды и по этим изменениям судят о концентрации искомого компонента.The method is used for research and analysis of materials using electromagnetic radiation. The inventive radiation source produces a signal of frequency w o , which is selected in the range of the significant second derivative of the refractive index of the desired component and, in the case of distance from this range, is adjusted to it by means of a block. With the help of a modulator, the carrier frequency ω o is modulated with the frequency Ω that the generator produces. Modulation is carried out according to amplitude or phase according to a certain (for example, harmonic) law. In the received radiation, the changes in time are recorded, respectively, of the phase or amplitude, and these changes are used to judge the concentration of the desired component.
