This invention discloses a light projector and a sensing system used in conjunction with the light projector. The light projector includes a light source and a diffraction optical element. The light source has a first light-emitting area and a second light-emitting area, and the diffraction optical element is disposed on the light source. The diffraction optical element has a first diffraction structure and a second diffraction structure, which overlap the first light-emitting area and the second light-emitting area, respectively. The first diffraction structure is different from the second diffraction structure.
