Abstract: A laser projection device has at least one laser light source and a plurality of gratings, each grating having a light receiving side and a light emitting side. The plurality of gratings are arranged in a ring-shape having at least one row with the light receiving side of each grating facing a center of the ring. The laser projection device also has a motor configured to rotate the plurality of gratings about a rotational axis passing through the center of the ring. The plurality of gratings each comprise a pattern for forming an image when light is passed through the pattern. The plurality of gratings are arranged around the ring such that the plurality of patterns are configured to project an animated image when the plurality of gratings sequentially receive light from the at least one laser light source upon rotation of the grating set.
