We developed and demonstrated a laser beam alignment system for micro laser projectors. This system measured the angle and position of each laser beam axis, and aligned them with the alignment stage. We could reduce the laser beam gap of each laser beam axis to 0.55′10-3° and 1.3 mm at a projection distance of 440 mm with this system. Also we showed that the size can be reduced to several cubic centimeters.
