Document Type and Number:
WIPO Patent Application WO/2018/004131
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a scanning projector comprises: a light source unit including an infrared light source for outputting an infrared light, and a plurality of color light sources; an optical system for synthesizing the lights outputted from the light source unit; a MEMS scanner for scanning in horizontal and vertical directions by outputting the synthesized light; a processor for generating a scanner driving signal driving the MEMS scanner; and a light sensing unit for sensing the infrared light, wherein the processor can change the scanner driving signal on the basis of a pattern change of the infrared light sensed by the light sensing unit.
