Abstract: The disclosure provides a laser lighting system. The laser lighting system includes a microcontroller, a motor, a fluorescent color wheel and a detection circuit. The motor drives the fluorescent color wheel to rotate. The detection circuit is configured to detect a detected signal from the fluorescent color wheel. When a synchronous signal changes, the microcontroller compares the detected signal to the synchronous signal, in order to control the output current signal for driving the motor, and to decrease the phase variation between the detected signal and the synchronous signal until the phase difference between the detected signal and the synchronous signal maintain at a constant value.

Abstract: An apparatus for intraoral scanning comprises an elongate wand comprising a probe at a distal end of the elongate wand. The apparatus further comprises one or more structured light projectors disposed within the probe, each structured light projector comprising: (a) a housing; (b) a light source disposed within the housing and comprising: a semiconductor laser die; and a beam shaping optical element; and (c) a pattern generating optical element. A distance D between an emission point of the semiconductor laser die and an input face of the beam shaping optical element is 50-250 microns. Each structured light projector is configured to project a pattern of light onto an intraoral surface when the light source of the structured light projector is activated to emit light through the pattern generating optical element of the structured light projector.
