Classification: CPC G  B | IPC B  G

Claim 0:
1. A head-up display system comprising:
an image generating apparatus configured to emit light having a first polarization and including image information;
a polarization beam splitter provided on an optical path of the light having the first polarization emitted by the image generating apparatus, the polarization beam splitter being configured to transmit the light having the first polarization;
a wave plate configured to transmit the light transmitted through the polarization beam splitter while converting a phase of the light; and
a mirror configured to reflect the light sequentially transmitted through the polarization beam splitter and the wave plate back to the polarization beam splitter through the wave plate,
wherein the polarization beam splitter is further configured to reflect light having a second polarization that is different from the first polarization, the light having the second polarization being generated when the light reflected by the mirror is transmitted back to the polarization beam splitter through the wave plate.
