LASER DIODE JUNCTION TEMPERATURE COMPENSATION

A projection apparatus includes at least one laser diode and a laser diode junction temperature estimator to estimate the junction temperature of the at least one laser diode. Laser diode current drive values are modified in response to the estimated laser junction temperature. The modification of l...

Beschreibung
Zusammenfassung:	A projection apparatus includes at least one laser diode and a laser diode junction temperature estimator to estimate the junction temperature of the at least one laser diode. Laser diode current drive values are modified in response to the estimated laser junction temperature. The modification of laser diode current drive values may occur as frequently as once per pixel.
