But you'd also need to fully account for the imaging optics (including non-idealities) and the absolute response of your sensor (volts or amps per unit incident flux). In practice, all of that gets captured by that one calibration constant, which can be determined by viewing the object once at a known temperature. The only thing that you have to account mathematically is the spectral sensitivity. | |

needed to expand the answer to properly cover the scope of the question
