METHOD OF MEASURING BRIGHTNESS TEMPERATURE AND PYROMETRIC CONVERTER FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC G01J5/52 G01K15/00 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment in the field of brightness pyrometry, can be used in metrology, in science, in industry and is intended for remote measurements of temperature of various heated objects. According to the disclosed solution, two reference radiation sources are used, which are used only for calibrating a pyrometric converter, which is carried out in advance in two steps. At the first calibration stage, the first reference radiation source is used and the coefficient of conversion of the power of the incident radiation to the pyrometric converter into its output signal is found which is average integral as per the given radiation spectrum. At the second calibration stage, the second reference radiation source is used and the area of the emitting surface of the second reference source, which corresponds to the specified sighting distance, is located. After performing the calibration at the specified distance, the object is viewed with a pyrometric converter, and its output signal is used to calculate the brightness temperature of the object. Pyrometric converter implementing the method comprises a band-pass optical filter with preset spectral transmission and a given Q-factor, an optical radiation receiver, a visual guidance device with a boresight distance measurement option, a microprocessor and an information display device. Band-pass optical filter is installed at the input of the optical radiation receiver, optical radiation receiver is formed by series-installed one after another objective lens with a given focal distance and a primary converter of optical radiation power into an electrical signal, and the primary power converter is connected to the microprocessor, the microprocessor is connected to the information display device.

EFFECT: technical result is reduction of duration of measurement process and reduction of element composition of device.
