    • An electroholographic display system (800, 900) for displaying a holographic image, includes a coherent light source (830, 930) producing a coherent, collimated, light beam; a spatial light modulator (SLM) (820, 920) adapted to receive and spatially modulate the coherent, collimated, light beam to produce therefrom a spatially modulated light beam including first portions having a first polarization and second portions having a second polarization orthogonal to the first polarization; and a processor and driver unit (810, 910) adapted to generate hologram data representing a holographic image and to apply appropriate voltages to the pixels of the SLM to cause the SLM to modulate the coherent collimated light beam with the hologram data. The spatially modulated light beam is projected to an image plane to produce the holographic image including the first portions having the first polarization and the second portions having a second polarization orthogonal to the first polarization.
    • 用于显示全息图像的电子照相显示系统(800,900)包括产生相干,准直光束的相干光源(830,930); 空间光调制器(SLR),其适于接收和空间调制所述相干平行的光束,从而产生空间调制的光束,所述空间调制光束包括具有第一偏振的第一部分和具有与所述第一极化正交的第二偏振的第二部分 第一极化 以及适于产生表示全息图像的全息图数据并且向SLM的像素施加适当电压以使SLM利用全息图数据调制相干准直光束的处理器和驱动单元(810,910)。 将空间调制的光束投影到图像平面,以产生包括具有第一偏振的第一部分和第二部分具有与第一偏振正交的第二偏振的全息图像。
