Micromirror Array Temperature Calculation using Illumination Power Density

The equations below are valid for each DMD in a single chip or multi-chip DMD system.

  • QILLUMINATION = (QINCIDENT × DMD average thermal absorptivity) (W)

  • QINCIDENT = ILLDENSITY × ILLAREA (W)

  • ILLDENSITY = measured illumination optical power density at DMD (W/cm2)

  • ILLAREA = illumination area on DMD (cm2)

  • DMD average thermal absorptivity = 0.40

QELECTRICAL = 3.26 W
Array size = 11.0592 mm × 6.4800 mm = 0.72 cm2
ILLDENSITY = 31 W/cm2 (measured)
TCERAMIC = 50.0 °C (measured)
ILLAREA = 0.72 cm2 / (83.7%) = 0.86 cm2
QINCIDENT = 31 W/cm2 × 0.86 cm2 =26.66 W
QARRAY = 3.26 W + (0.40 × 26.66 W) = 13.92 W
TARRAY = 50.0 °C + (13.92 W × 0.90 °C/W) = 62.53 °C
