    • Light combiners and light splitters, and methods of using light combiners and light splitters are described. In particular, the description relates to light combiners and splitters that combine and split, respectively, light of different wavelength spectrums using polarizing beam splitters. The polarizing beam splitters include a reflective polarizer to efficiently split incident light into transmitted and reflected beams having different polarization directions. Reflectors and quarter-wave retarders are positioned facing selected prism faces of the polarizing beam splitters, to affect the polarization state of light passing through the prism faces. The reflectors can be dichroic filters adapted to reflect light that is outside a selected wavelength range, so that light of different wavelength spectrums can be affected at different prism faces. The surfaces of each polarizing beam splitter can be polished so that the light utilization efficiency is increased due to total internal reflection within the polarizing beam splitter. The light combiners can combine up to five unpolarized different color lights to produce an unpolarized polychromatic light output, which may be white light useful for a projection display. The light splitters can split unpolarized polychromatic light to produce up to five unpolarized different color light outputs.
    • 光组合器和光分离器以及使用光组合器和分光器的方法被描述。 特别地,该描述涉及使用偏振分束器分别组合和分离不同波长光谱的光的光组合器和分束器。 偏振分束器包括有效地将入射光分离成具有不同偏振方向的透射和反射光束的反射偏振器。 反射器和四分之一波长延迟器被定位在偏振分束器的选定的棱镜面上,以影响穿过棱镜面的光的偏振状态。 反射器可以是适于反射在选定波长范围外的光的二向色滤光片,使得不同波长光谱的光可以在不同的棱镜面受到影响。 每个偏振分束器的表面可以被抛光,使得由于偏振分束器内的全内反射而增加光的利用效率。 光组合器可以组合多达五个非偏振的不同颜色的光以产生非偏振多色光输出,其可以是用于投影显示的白光。 分光器可以分离非偏振多色光,产生多达五个非偏振的不同颜色的光输出。

    • A projection system includes a projection lens unit, a color combiner, and at least a first and a second image-forming devices for generating single color images. The single color images are combined in the color combiner to produce a colored image light beam. The colored image light beam passes from the color combiner to the projection lens system. A polarization control element is disposed between the color combiner and the first image-forming device. The polarization control element alters the polarization of light at either one of the first and second color, while not altering the polarization of light of the other of the first and second color. In some embodiments, the polarization control element is oriented to substantially prevent light at the second color from passing from the color combiner to the first image-forming device via a polarizing beamsplitter.
    • 投影系统包括投影透镜单元,颜色组合器以及用于产生单色图像的至少第一和第二图像形成装置。 单色图像在组合器中组合以产生彩色图像光束。 彩色图像光束从组合器​​到投影透镜系统。 偏光控制元件设置在彩色组合器和第一图像形成装置之间。 偏振控制元件改变第一和第二颜色中的任何一个处的光的偏振,同时不改变第一和第二颜色中的另一个的光的偏振。 在一些实施例中,偏振控制元件取向为基本上防止第二种颜色的光通过偏振分束器从分色器通过第一成像装置。

    • An optical system and a projection system incorporating same are disclosed. The optical system includes first and second optical elements. The second optical element is polarization insensitive in the visible. The first optical element is capable of receiving light of a first polarization along a first direction and transmitting the received light along the first direction. The first optical element is also capable of receiving light of a second polarization orthogonal to the first polarization along the first direction and reflecting the received light along a second direction different from the first direction. When the optical system receives light of the first polarization along the second direction, the first optical element transmits the received light along the second direction. The transmitted light has the first polarization and a first set of color coordinates. The second optical element transmits at least a portion of the light transmitted by the first optical element. The light transmitted by the second optical element has a second set of color coordinates that is different from the first set of color coordinates.
