Patent attributes
A structured light projector is disclosed, which includes a first light source, a second light source, an optical refractive element and an optical shaper. The first light source and the second light source are configured to respectively emit first incoherent light and second incoherent light. The optical refractive element is arranged over the first and second light sources for refracting the first incoherent light and the second incoherent light. The optical shaper element is arranged over the optical refractive element for shaping the first incoherent light to generate first structured light with plural first optical patterns and shaping the second incoherent light to generate second structured light with plural second optical patterns, in which the first structured light and the second structured light are overlapped onto a region of space.
