ABSTRACT:
A compact displaying optical system capable of reducing a speckle noise and a loss of light amount is disclosed. The displaying optical system which projects images using coherent light, comprises a light source which emits the light; and a polarization control unit. The polarization control unit changes the polarization state of the light emitted from the light source temporally.
