Abstract
Aspects of the disclosure provide an optical system. The optical system includes a polarization controller that controls polarization states of light beams such that a polarization state of each light beam passing through the polarization controller has one of a first polarization state and a second polarization state. The optical system includes a beam splitter, a reflective polarizer, and one or more lenses between the beam splitter and the reflective polarizer. If a polarization state of a first light beam of the light beams that passes through the polarization controller has the first polarization state, the first light beam passes the one or more lenses only one time. If a polarization state of a second light beam of the light beams that passes through the polarization controller has the second polarization state, the second light beam passes the one or more lenses more than one time.
