FIELD: physics, computer engineering.
SUBSTANCE: invention relates to a method and a system for analysing or inspecting people or other objects for presence of foreign or native materials. The method employs parallel-mode spectroscopy, which comprises generating a probing signal simultaneously containing electromagnetic radiation with a wide bandwidth in the range of 10 GHz to 25 THz. Said range enables simultaneous detection of a plurality of signals at a plurality of frequencies. Each signal has certain amplitude, which collectively provides a unique spectral signature of the material. Processing of the obtained data comprises presenting said data in matrix form. Correlation method is used to compare the obtained matrix data with a reference library.
EFFECT: providing real-time operation.
