Claim 13:
14. A head-up display system comprising:
an image generating apparatus configured to emit light having a first polarization and including image information;
a first polarization beam splitter provided on an optical path of the light having the first polarization and configured to reflect the light having the first polarization;
a first wave plate configured to transmit the light reflected by the first polarization beam splitter while converting a phase of the light;
a first mirror configured to reflect the light transmitted through the first wave plate back to the first polarization beam splitter through the first wave plate;
a second wave plate spaced apart from the first wave plate with the first polarization beam splitter therebetween, the second wave plate being configured to transmit the light reflected by the first mirror and sequentially transmitted through the first wave plate and the first polarization beam splitter while converting the phase of the light; and
a second mirror configured to reflect the light sequentially transmitted through the first polarization beam splitter and the second wave plate back to the first polarization beam splitter through the second wave plate,
wherein the first polarization beam splitter is further configured to reflect the light reflected by the second mirror and transmitted back through the second wave plate.
