Abstract
An optical system is disclosed. The optical system includes collimating optics, including a polarization beam splitter, which includes one or more polarizations selection reflection surfaces configured to split image light into (s)-polarized light and (p)-polarized light. The collimating optics further include a first mirror configured to receive and reflect (p)-polarized light emitted from the one or more polarization selective reflection surfaces, a second mirror configured to receive and reflect (s)-polarized light emitted from the one or more polarization selective reflection surface, and a corrector lens configured to receive (p)-polarized light reflected from the first mirror and receive (s)-polarized light reflected from the second mirror, wherein a light path of the (s)-polarized light and a light path of the (p)-polarized light are substantially equal, wherein the (p)-polarized light and the (s)-polarized light are configured to combine to form a user image.
