MULTICHANNEL CONFOCAL IMAGE SPECTRUM ANALYZER Russian patent published in 2020 - IPC G01J3/02 G01N21/25 

FIELD: spectroscopic analysis.

SUBSTANCE: invention relates to spectroscopic analysis and relates to a multichannel confocal image spectrum analyzer. Spectrum analyzer includes a diode laser, cylindrical optics, a confocal diaphragm, a lens, a video camera, a scanning system and a data processing system. Cylindrical optics includes three cylindrical lenses. First lens forms a collimated radiation beam scattered by the diffraction grating. Second lens localizes the interference orders in the plane in which the slit diaphragm and object plane of the objective lens are formed, which forms laser radiation in the form of a line on a given scale. Third lens is arranged so that the laser emitting platform and the slit of the confocal diaphragm are located in the conjugate planes of this lens. Radiation from the object returns through the lens, passes through the slit, is converted by the second lens into a collimated beam and is decomposed into the spectrum by a diffraction grating. First diffraction order is localized with a camera lens on a two-dimensional matrix of a video camera.

EFFECT: technical result consists in increase in information content of images, simple design and increase in scanning speed.
