ULTRA-COMPACT HIGH-RESOLUTION SPECTROMETER AND ITS APPLICATION METHOD Russian patent published in 2019 - IPC G01J3/45 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment, and relates to the spectrometer for the light intensities spectrum analyzing. Spectrometer contains a rigidly mounted collimator, a rigidly fixed optical element, a measuring unit, a memory unit, a processing unit and a display unit. Optical element is made with the possibility of the collimated light separation to at least two converging beams. From the optical element, the measurement unit is located at a distance, which corresponds to the two converging beams interference region, and is made with possibility of the light intensities spectrum production. Memory unit stores the database including the set of corresponding to the particular type of sample reference intensities spectra. Processing unit is connected to the measurement unit and configured to select a reference spectrum, corresponding to the same type of samples as the sample under study, and to determine, whether the obtained intensities spectrum corresponds to the reference intensities spectrum. Display unit is configured to display the determination result.

EFFECT: design simplification and increase in the spectral resolution.
