Claim 14:
15. The projection system according to claim 9, wherein the polarized light converting component comprises a quarter-wave plate and a reflective mirror; wherein
the quarter-wave plate is disposed between the reflective mirror and the polarizing beam splitting prism, and the quarter-wave plate and the reflective mirror are both parallel to the first direction;
the quarter-wave plate is configured to rotate a polarization state of the S-polarized light reflected from the polarizing beam splitting prism by 45 degrees to acquire an intermediate light, and emit the intermediate light to the reflective mirror;
the reflective mirror is configured to reflect the intermediate light emitted from the quarter-wave plate to the quarter-wave plate; and
the quarter-wave plate is further configured to rotate a polarization state of the intermediate light reflected from the reflective mirror by 45 degrees to acquire a P-polarized light, and emit the P-polarized light to the polarizing beam splitting prism.
