Abstract
The present disclosure provides a laser projection device and a laser projection system. The laser projection device comprises an optical fiber scanner and a MEMS scanning mirror; an optical fiber is disposed on the optical fiber scanner and the optical fiber is used to deliver laser beams needed by projection; the optical fiber scanner drives the optical fiber to scan in a first plane and enables the laser beam to project to the MEMS scanning mirror; and the MEMS scanning mirror makes scanning movement about a first axis and reflects the laser beam to a predetermined area to form a projection image; wherein the first axis is located in the first plane, or the first axis is parallel to the first plane. The present disclosure achieves laser projection by enabling the optical fiber scanner and the MEMS scanning mirror to scan simultaneously in different directions.
