The active array temperature can be computed analytically from the temperature sense diode measurement, the thermal resistance from array to diode, the electrical power, and the illumination heat load. The relationship between array temperature and the temperature sense diode is provided by the following equations:
where
The temperature sense diode to array thermal resistance (RARRAY–TO–DIODE) assumes a uniform illumination distribution on the DMD.
The following sample calculations assume 10% of the total incident light falls outside of the active array and POM, and the mirrors are in the OFF state.
