Title:
LASER PROJECTOR, CAMERA MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/201010
Kind Code:
A1
Abstract:
A laser projector (10), comprising a substrate assembly (11), a barrel assembly (12), a light source (13), a collimating element (14), and a diffraction element (15). The barrel assembly (12) is provided on the substrate assembly (11). The barrel assembly (12) comprises a first component (121) and a second component (122) which are movably connected to each other. The first component (121) is provided on the substrate assembly (11). The light source (13) is provided on the substrate assembly (11). The collimating element (14) is mounted on the barrel assembly (12), and is used for collimating the laser light emitted from the light source (13). The light source (13) is an edge emitting laser. The edge emitting laser comprises a light emitting surface (131), and the light emitting surface (131) faces the collimating element (14). The diffraction element (15) is provided on the second component (122) for diffracting the laser light collimated by the collimating element (14) to form a laser pattern. Also disclosed are a camera module (100) comprising the laser projector (10) and an electronic device (1000) comprising the camera module (100).
