摘要
The present disclosure provides a vertical-cavity surface-emitting laser, structured light module, terminal comprising the structured light module, and method for projecting the structured light thereof. The structured light module includes a plurality of light sources and a single diffractive optical element (DOE); wherein the plurality of light sources simultaneously emit a plurality beams of invisible light to the single DOE, wherein the single DOE has a pseudo-random optical pattern groove, wherein the invisible light of each light source passes through the DOE and emits a beam of spectral encoded structured light , and the beam of structured light comprises a pattern corresponding to the pseudo-random optical pattern groove. The DOE projects an overall structured light that is formed by superimposing a plurality of beams of structured light, and there is an offset between patterns of different beams of structured light.
