FIELD: physics.
SUBSTANCE: device has a photodiode, a differential amplifier, a power supply, a variable resistor, a voltage source, an analogue-to-digital converter and a computing device. The output of the device is the output of the differential amplifier.
EFFECT: high accuracy of measuring temperature of heated surfaces by reducing the effect of emissivity of the radiating surface of the inspected object and reducing the effect of transfer constants of the amplification and conversion circuits, high linearity of conversion while maintaining a dynamic range without deterioration in sensitivity of the device in a wide range of operating temperature of the photodetector.
