Abstract

The effective blackbody temperature used to specify the radiant output from an IR projector is defined formally as the temperature assumed by the blackbody target that generates the same signal radiance as the IR projector characterized. Analytical expressions and graphical analyses are developed enabling the calculation of the blackbody temperature in terms of both the actual device temperature and a specified active zone attenuation coefficient, the latter quantifying the deviation from blackbody behavior. Both the projector signal radiance and the signal current developed in the imaging unit under test illuminated by the projector are shown to be readily calculable once the value of the effective blackbody temperature is known. The analysis is applied to the comparison of the thin film resistor, silicon bridge resistor, and suspended membrane resistor emissive IR projection technologies.
