2 Calculating Mirror Surface Temperature With Pulsed Optical Sources

Absorbed heat is input on top of the DMD mirror, causing the top surface of the mirror to be the hottest location. The mirror surface temperature will rise and fall as pulsed illumination is applied, and the three temperature rises described previously can be calculated individually and added together to find the resulting mirror surface temperature.
