中文摘要：

为实现傅里叶计算全息图的真彩色显示,本文提出了一种时空复用方法。首先对一幅彩色场景进行红绿蓝分色,并按照一定的比例对三色场景进行缩放处理,实现真彩色再现像的色差补偿;然后制作3幅具有特定结构的全息图,将3幅全息图轮流加载到空间光调制器上,通过时空复用保证了彩色再现像信息的完整性;最后通过使用滤光片,实现以白光LED作为再现光源的真彩色全息显示。结果验证了所提出方法的可行性。

英文摘要：

Using a simple optic system to realize full-color holographic display is the goal of the promising three-dimensional displays.In this paper,we propose a full-color display of Fourier computer-generated hologram using spatiotemporal multiplexing method.First,we divide a color image into red,green and blue components,and make a proper scaling in order to compensate chromatic aberrations.Then three Fourier computer-generated holograms with specific structure are made,which are displayed on the spatial light modulator in turns.By using the spatiotemporal multiplexing method,we can ensure the information integrity of the reconstructed color image.At last,we design a filter so that the white LED can be used as the reconstructed light.The experiment results verify the feasibility of the method.
