一种全息显示装置及方法
摘要：
本发明涉及全息显示技术领域，公开了一种全息显示装置及方法，其中，全息显示装置包括：至少两个液晶空间光调制器；图像信息写入器，用于将一个全息图的图像信息写入所述至少两个液晶空间光调制器中，且所述至少两个液晶空间光调制器中写入的图像信息不同；光源模块，用于为所述至少两个液晶空间光调制器提供读出光；聚光器，用于将所述至少两个液晶空间光调制器的输出光汇聚成像。本发明提供的全息显示装置，在单位时间内能够输出更多物光波的图像信息，从而可以大大提高全息图像的刷新频率，有效改善全息图像再现效果。
摘要（英）：

The invention relates to the technical field of holographic display and discloses a holographic display device and a holographic display method. The holographic display device comprises at least two liquid crystal spatial light modulators. An image information writer for writing image information of one hologram into the at least two liquid crystal spatial light modulators, and the image information written in the at least two liquid crystal spatial light modulators is different; A light source module for providing readout light to the at least two liquid crystal spatial light modulators; A condenser for condensing and imaging the output light of the at least two liquid crystal spatial light modulators. The holographic display device provided by the invention can output more image information of the object light wave in unit time, thereby greatly increasing the refresh frequency of the hologram image and effectively improving the hologram image reconstruction effect.
