SYSTEM FOR FORMING BROADBAND HYPERSPECTRAL IMAGE BASED ON COMPRESSIBLE PROBING WITH A RANDOM DIFFRACTION GRATING Russian patent published in 2018 - IPC G01J3/28 

FIELD: electrical communication engineering.

SUBSTANCE: present invention relates to systems for forming broadband hyperspectral images based on compressible probing, namely, to systems for forming a broadband hyperspectral image based on compressed probing with a random grating. System for forming a broadband hyperspectral image based on compressed probing with a random grating, comprising a receiving imaging system, a beam splitter component, more than two channels and a computer, in each channel there is a component that converts the exit pupil and a component that compresses a spectral image. System is based on the compressed probing theory. Using the correlation between the spectra, it increases the compression ratio in the spectral measurement, collects the compressed three-dimensional data on the broadband spectral image and significantly reduces the amount of obtained data.

EFFECT: system is able to process information obtained in a wide range in one exposure and allows to achieve a large spatial and spectral resolution by means of selected random diffraction gratings in different receiving channels.
