A real-time full-color phase-only holographic display system generates holograms of 3D objects. The system includes a 3D object formed by voxels, an internet-based transmission capability that transmits the object information to the server, a real-time hologram generation unit, and a holographic display unit with incoherent illumination. The server calculates three phase holograms for RGB components using multiple GPUs. The resultant phase holograms are saved into an RGB bitmap image and loaded to the phase-only spatial light modulators (SLMs). SLMs are illuminated uniformly by LEDs, and reconstructed waves are aligned and overlapped by using high precision optics and stages. Experimental results are satisfactory.
一种实时全彩色纯相位全息显示系统可生成三维物体的全息图。该系统包括由体素构成的三维物体、将物体信息传输到服务器的基于互联网的传输能力、实时全息图生成单元以及具有非相干照明的全息显示单元。服务器使用多个图形处理器为RGB分量计算三个相位全息图。所得的相位全息图被保存为RGB位图图像，并加载到纯相位空间光调制器（SLM）中。SLM由发光二极管均匀照明，并且通过使用高精度光学器件和平台使重建波对准并重叠。实验结果令人满意。
