Computational holography requires a large amount of time to generate holograms. One of methods to solve this problem is a fast computation of Fresnel holograms using separable convolution. In this study, we propose a separable Fraunhofer hologram that can compute holograms faster. In addition, we derive a suitable recurrence formula for the proposed method. In this study, we compare the image quality and computation speed of the proposed method with those of conventional methods. In addition, dedicated computers using a field programmable gate array (FPGA) have been developed, but the conventional algorithm has a problem of increasing the complexity of the computational circuits. In this study, we show that the proposed method can simplify the calculation circuits. |
