EDITOR’S … WebTo calculate the emissivity matrix we heat the target to two known uniform temperatures and measure the total radiances of the target (T 2 > T 1), which are converted to target radiance via the calibration lookup table. Assuming that the radiation representing the reflected environment is unchanged, they are eliminated between the two.
