FIELD: physics, measurement.
SUBSTANCE: The method involves correction of calibration correspondence on the basis of reference and test value ratio for output signal swing, the first one measured in calibration mode, the second measured in measurement mode. Reference and test output signal swing measurement is performed in the centre of photosensitive surface of photoreceiver, lit by reference luminance source with luminance distribution close to uniform. It reduces image element detection error effect significantly.
EFFECT: enhanced accuracy of luminance temperature measurement.
