The light source is configured to provide a light beam. The reflective spatial polarization modulator is disposed on a path of the light beam and configured to reflect the light beam and modulate a polarization state of the light beam. The polarization grating is disposed on the path of the light beam between the light source and the reflective spatial polarization modulator, wherein the reflective spatial polarization modulator reflects the light beam from the reflective spatial polarization modulator back to the polarization grating.
