More Information
Summary:Provided is a holographic display apparatus capable of providing an expanded viewing window when reproducing a holographic image via an off-axis technique. The holographic display apparatus includes a spatial light modulator comprising a plurality of pixels arranged two-dimensionally; and an aperture enlargement film configured to enlarge a beam diameter of a light beam coming from each of the plurality of pixels of the spatial light modulator. The beam diameter of each light beam enlarged by the aperture enlargement film may be greater than the width of an aperture of each pixel of the spatial light modulator. 提供一种全息显示设备，当经由离轴技术再现全息图像时，该全息显示设备能够提供扩大的观看窗口。全息显示设备包括：空间光调制器，包括二维布置的多个像素；以及孔扩大膜，配置为扩大来自空间光调制器的所述多个像素中的每个的光束的光束直径。被孔扩大膜扩大的每个光束的光束直径可以大于空间光调制器的每个像素的孔的宽度。
