    • A light modulator assembly includes first, second, and third light modulators, with first and second dichroic mirrors. The first dichroic mirror is located at an optical pupil of said assembly and is configured to split a beam of light into a first component beam and an intermediate beam. The first dichroic mirror then transmits the first component beam to the first light modulator and reflects the intermediate beam to the second dichroic mirror. The second dichroic mirror is configured to split the intermediate beam into second and third component beams and to direct the second component beam to the second modulator and the third component beam to the third modulator. A third dichroic mirror is configured to receive the output of the first, second, and third modulators and to pass the output from the first, second, and third modulators to display optics.
    • 光调制器组件包括具有第一和第二分色镜的第一,第二和第三光调制器。 第一分色镜位于所述组件的光学瞳孔处,并被配置为将光束分成第一分量光束和中间光束。 然后,第一分色镜将第一分量光束传输到第一光调制器,并将中间光束反射到第二分色镜。 第二分色镜被配置为将中间光束分成第二和第三分量光束并将第二分量光束引导到第二调制器,将第三分量光束引导到第三调制器。 第三分色镜被配置为接收第一,第二和第三调制器的输出,并将输出从第一,第二和第三调制器传递到显示光学器件。

    • A prism assembly includes a first prism having a first front face, a first side face, and a first rear face, a second prism having a second front face parallel to the first rear face, a second side face, and a second rear face. The second prism is configured to direct a first component beam through the second side face. The prism assembly also includes a third prism having a third front face parallel to the second rear face, a third side face, and a third rear face. The third prism is configured to direct a second component beam through the third side face. The prism assembly also includes a fourth prism having a fourth front face parallel to the third rear face and a fourth rear face, the rear face being parallel to the first front face. The fourth rear face is configured to transmit a third component beam there through.
