    • A color display apparatus having a virtual single light origin is disclosed. The color display apparatus includes an illumination lens system, a combining system, a Fourier filter and a projection system. The illumination lens system converts a plurality of light beams, which are radiated from a plurality of light sources, into linear, parallel light beams. The combining system produces a plurality of diffracted light beams having a plurality of diffraction orders by modulating each of the parallel light beams incident from the illumination lens, and outputs the plurality of diffracted light beams so that the diffracted light beams have a same virtual light origin and are adjacently located. The Fourier filter passes only some of the diffracted light beams, which have desired diffraction orders, therethrough. The projection system focuses the diffracted light beams, which are passed through the Fourier filter, on an object, and then allows the focused diffracted light beams to scan the object.
    • 公开了一种具有虚拟单光源的彩色显示装置。 彩色显示装置包括照明透镜系统,组合系统,傅里叶滤波器和投影系统。 照明透镜系统将从多个光源辐射的多个光束转换为线性平行光束。 组合系统通过调制从照明透镜入射的每个平行光束产生多个衍射级的多个衍射光束,并且输出多个衍射光束,使得衍射光束具有相同的虚拟光源 并相邻。 傅里叶滤波器仅通过其中具有期望的衍射级的一些衍射光束。 投影系统将通过傅立叶滤波器的衍射光束聚焦在物体上,然后允许聚焦的衍射光束扫描物体。
