DEVICE FOR NON-CONTACT MEASUREMENT OF THE TEMPERATURE FIELD ON THE OBJECT SURFACE Russian patent published in 2023 - IPC G01J5/00 G01J5/02 

FIELD: thermophysical measurements.

SUBSTANCE: invention relates can be used for non-contact measurement of the temperature field on the surface of an object, in particular a printed circuit board of a radio electronic device. A device for non-contact measurement of the temperature field on the surface of an object is claimed, containing a chamber in which a heater is installed, controlled by a signal from the first output of the thermal control unit, as well as an object and a reference emitter optically connected to the optical unit through a transparent window in the chamber, a control unit, as which a control computer is used, a radiation detection unit of an object whose input is connected to the first output of the optical unit, and the output is connected to the first input of the control computer, a radiation detection unit of a reference radiator, which is used as a model of an absolute blackbody (ABB) and whose input is connected to by the second output of the optical unit, the emissivity calculation unit, the input of which is connected to the first output of the blackbody model radiation registration unit, and the output is connected to the second input of the control computer, as well as the first and second thermocouples and the first and second operational amplifiers.

EFFECT: expanding the functionality of the device and increasing the accuracy of non-contact measurement of temperature fields (distributions) on the surface of an object with complex reliefs.
