Изобретение относится к области аналитического приборостроения и может быть использовано при разработке контрольно-измерительной техники. Сущность изобретения : способ определения спектральных характеристик исследуемых объектов заключается в формировании модулированных сигнала синхронизации и аналитических сигналов, один из которых, по крайней мере, пропускают через образец, измерении сдвига фаз относительно сигнала синхронизации, по которому судят о параметрах исследуемого объекта, причем модуляцию сигналов осуществляют по гармоническому закону, обеспечивая сдвиг фаз на величину, не равную πn по крайней мере для пары аналитических сигналов, где n - произвольное целое число, и до измерения сдвига фаз осуществляют суммирование аналитических сигналов. Кроме того, сдвиг фаз может быть равен величине

The invention relates to the field of analytical instrumentation and can be used in the development of instrumentation technology. The inventive method for determining the spectral characteristics of the objects under study consists in generating a modulated synchronization signal and analytical signals, one of which is at least passed through the sample, measuring the phase shift relative to the synchronization signal, which is used to judge the parameters of the object under study according to the harmonic law, providing a phase shift by an amount not equal to πn, at least for a pair of analytical signals, where n is an arbitrary integer h The number and the measurement of the phase shift carry out the summation of analytical signals. In addition, the phase shift can be equal to
