DEVICE FOR DETERMINING SPECTRAL EMISSIVITY OF HOT OBJECTS Russian patent published in 2010 - IPC G01J3/00 

FIELD: physics.

SUBSTANCE: in the device the number of spectral bands N is greater than 6. The device includes N independent radiation receivers, N analogue-to-digital converters (ADC), N memory units, N dividers, a synchroniser, as well as a channel for determining temperature of the measured object. The optical input of the radiation receiver in each channel is connected to a beam splitter and the electrical output is connected to the input of the corresponding ADC, whose first output is connected to the first input of the corresponding divider, the second output of the ADC is connected to the input of the corresponding memory unit whose output is connected to the second input of the divider, outputs of the dividers are connected to inputs of a recording device.

EFFECT: higher accuracy of measuring spectral emissivity of hot objects.
