Holography is the ultimate three-dimensional (3D) imaging technology, and research is actively being conducted on generating at high-speed holograms with enormous amounts of information and improving image quality. Because computer holography is based on wave optics algorithms, reconstructing the texture of 3D images is difficult. On the other hand, in principle, reconstructing texture in integral photography based on geometric optics is easy and the method is well established. We developed a high-performance special-purpose computer, called holographic reconstruction for ultra-realistic imaging, dedicated to the ray-wavefront conversion method. The design and implementation of the circuit for the hologram generation were performed using field-programmable gate array technology. Parallelization was performed at each step for increasing the speed of the calculation process. Furthermore, by sending output data directly to a displaying device in the high-definition multimedia interface, the communication between the host personal computer (PC) and special-purpose computer was controlled in one direction, which significantly reduced communication time. The system was ∼7.7 times faster than a PC alone and succeeded in the holographic reproduction of a textured 3D image in real time at 30 frames per second for a 1024 × 1024-pixel hologram.

专用于射线波前转换技术的高性能计算机系统，旨在实时显示全息图

全息术是终极三维（3D）成像技术，人们正在积极进行研究以生成具有大量信息的高速全息图并提高图像质量。由于计算机全息术基于波动光学算法，因此重建 3D 图像的纹理很困难。另一方面，原则上，基于几何光学的积分摄影中的纹理重建很容易，而且方法也很成熟。我们开发了一种高性能专用计算机，称为超真实成像全息重建，专用于射线波前转换方法。全息图生成电路的设计和实现是使用现场可编程门阵列技术进行的。每一步都进行并行化以提高计算过程的速度。此外，通过将输出数据直接发送到高清多媒体接口中的显示设备，可以单向控制主机个人计算机（PC）和专用计算机之间的通信，从而大大减少了通信时间。该系统比单独的 PC 快约 7.7 倍，并成功以每秒 30 帧的速度实时全息再现纹理 3D 图像，形成 1024 × 1024 像素全息图。这大大减少了沟通时间。该系统比单独的 PC 快约 7.7 倍，并成功以每秒 30 帧的速度实时全息再现纹理 3D 图像，形成 1024 × 1024 像素全息图。这大大减少了沟通时间。该系统比单独的 PC 快约 7.7 倍，并成功以每秒 30 帧的速度实时全息再现纹理 3D 图像，形成 1024 × 1024 像素全息图。
