| 摘要 |
<p>The invention relates to an image projection system (1). The system comprises an illumination system (3) with a radiation source (5) and a modulation system comprising at least one reflective image display panel (15). The system (1) further comprises a projection lens system (18). A polarization-sensitive beam splitter (17) is arranged between the illumination system (3) and the image display panel (15). The illumination system (3) comprises an integrator system (9) having a first and a second integrator plate (11, 13). A third integrator plate (27) is arranged in the plane of the second integrator plate (13). A reflecting element (29) is arranged between the third integrator plate and its focal plane. The system comprises an optical system for imaging, at least partly, the reflected image of the second integrator plate on the third integrator plate.</p> |
