METHOD OF CONTACTLESS MEASUREMENT OF SPATIAL DISTRIBUTION OF TEMPERATURE AND EMISSIVITY OF OBJECT Russian patent published in 2020 - IPC G01J1/22 

FIELD: measurement technology.

SUBSTANCE: invention relates to techniques for remote measurement of spatial distribution of temperature and emissivity on the surface of objects. Disclosed is a method for contactless measurement of spatial distribution of temperature and emissivity of an object, in which a beam of broadband radiation coming from an object is formed, performing spectral filtration of said beam with an acousto-optic filter, focusing the filtered radiation and forming an image of the object, recording the image of the object with a matrix radiation receiver, and digital processing of the image. A mosaic bitmap consisting of a given number of different light filters is installed on the matrix radiation receiver, simultaneously selecting spectral channels, number and maximums of which correspond to transmission bands of spectral light filters of the mosaic raster, by means of an acoustooptical filter operating in k-frequency mode, where k is number of pass bands of spectral light filters of the mosaic raster.

EFFECT: possibility of simultaneous registration of multiple digital images in narrow spectral intervals within a wide range of wavelengths of electromagnetic radiation.
