Abstract
The present invention provides a projector including a laser module and a lens module, wherein the lens module includes a plurality of lens and a plurality of diffractive optical elements. In the operations of the projector, the laser module is arranged to generate at least one laser beam; each of the lenses is arranged to receive one of the at least one laser beam to generate a collimated laser beam; and the diffractive optical elements correspond to the lenses, respectively, and each of the diffractive optical elements is arranged to receive the collimated laser beam from the corresponding lens to generate an image. The images generated by the diffractive optical elements form a projected image of the projector. By using the projector of the present invention, the projected image may have higher resolution or field of view that is advantageous for the 3D sensing system.
