Abstract
The present invention provides a projector including a light-emitting device, a diffraction optical element (DOE) and a switchable diffuser. The light-emitting device is arranged for generating a laser beam. The switchable diffuser is controlled by a control signal to diffuse or scatter received lights or not diffuse or scatter the received lights, wherein the laser beam passes through the DOE and the switchable diffuser to generate an output image of the projector.
