在中央处理器(CPU)、图形处理器(GPU)和多GPU计算平台上实现了快速生成数字全息图的近似方法。对该方法在各平台上的计算性能进行了测试和比较。该算法在GPU平台上的计算速度远快于CPU平台,在多GPU平台上可以进一步加速。此外,还对单精度和双精度算法的精度进行了评价。采用单精度算法重建的图像质量与采用双精度算法重建的图像质量相当,因此采用单精度算法在多gpu平台上实现可用于全息视频显示。
An approximation for fast digital hologram generation is implemented on a central processing unit (CPU), a graphics processing unit (GPU), and a multi-GPU computational platform. The computational performance of the method on each platform is measured and compared. The computational speed on the GPU platform is much faster than on a CPU, and the algorithm could be further accelerated on a multi-GPU platform. In addition, the accuracy of the algorithm for single- and double-precision arithmetic is evaluated. The quality of the reconstruction from the algorithm using single-precision arithmetic is comparable with the quality from the double-precision arithmetic, and thus the implementation using single-precision arithmetic on a multi-GPU platform can be used for holographic video displays.
