  • Projection module, structured light three-dimensional imaging device and electronic apparatus
    Patent number: 11467419
    Abstract: Disclosed are a projection module, a structured light three-dimensional imaging device, and an electronic apparatus. The projection module includes a laser emitter and a reflective grating. The laser emitter includes a light emitting surface from which laser light is emitted. The reflective grating includes a reflecting surface arranged obliquely relative to the light emitting surface and opposite to the light emitting surface. The reflective face is provided with a grating microstructure thereon. The projection module can adjust a reflection angle of the laser light when expanding beams to generate a laser pattern.
