METHOD OF CONTACTLESS MEASUREMENT OF SPATIAL DISTRIBUTION OF TEMPERATURE AND EMISSIVITY OF OBJECTS WITHOUT SCANNING

摘要

FIELD: measuring equipment.;SUBSTANCE: invention relates to the field of measurement equipment and concerns a method of contactless measurement of spatial distribution of temperature and emissivity of objects without scanning. Method involves forming a light beam of broadband radiation coming from an object, focusing radiation and forming an image of the object, recording the image of the object with a matrix radiation receiver and digital image processing. Separation of the light beam is carried out using a lens raster between the optical system and the radiation matrix receiver and consisting of a given number of lenses which focus the images on the radiation matrix receiver. Detection of spatially spaced spectral images of the object is performed by a grid arranged in front of the matrix radiation detector, consisting of light filters, the number and position of which correspond to the number and position of the lenses in the lens raster. Transmission curves of light filters correspond to preset positions of spectral channels.;EFFECT: technical result consists in enabling determination of temperature distribution and emissivity on the surface of objects without mechanical or spectral scanning.;1 cl, 1 dwg
