我们提出了一种数值方法，用于重建大型物体使用卷积方法与可调放大率。该方法是基于照明光束为球面波阵面时全息像的位置和放大率关系。角谱传递函数的修改版本，提出了允许在空间频谱中的过滤。实验结果证实了所提出的方法的适用性。
We present a numerical method for reconstructing large objects using a convolution method with an adjustable magnification. The method is based on the image locations and magnification relations of holography when the illuminating beam is a spherical wavefront. A modified version of the angular spectrum transfer function is proposed that allows the filtering in the spatial frequency spectrum. Experimental results confirm the suitability of the proposed method.
