INSTALLATION AND METHOD OF MEASURING THICKNESS OF WALLS OF GLASS VESSELS Russian patent published in 2024 - IPC G01B11/06 G01N33/38 

FIELD: optics.

SUBSTANCE: invention relates to the technical field of optical control of transparent or transparent vessels or hollow objects having a high temperature. Method of measuring thickness of walls of glass vessels coming out of moulding cavities, in which heat radiation emitted by vessel from diametrically opposite sides of vessel is selected for measurement. Radiation emitted by the vessel in the first spectral band (λ1) in range from 2800 nm to 4000 nm and in the second spectral band (λ2). At the same time measuring: on the first side (I) of the vessel, intensity of radiation emanating from first wall (21), in the first spectral band (λ1) and in the second spectral band (λ2); and on the second side (II) of the vessel, the intensity of the radiation emanating from second wall (22) in the first spectral band (λ1) and in the second spectral band (λ2). Determining the thickness of the first and second walls (2₂) based on measurements of the intensity of radiation emanating from the first wall, in the first and second spectral bands and from the second wall, in the first and second spectral bands, Note here that the radiation intensity in the first spectral band is taken into account for the radiation emitted by the wall itself and radiation emitted by the other diametrically opposite wall and passing through the said wall with absorption.

EFFECT: high accuracy of determining thickness of walls of glass vessels at high temperature.
