Abstract

We propose an adaptive point-spread spherical wave synthesis method based on the point-source hologram technique for fast hologram pattern generation. The calculation time of the hologram generation is reduced by decreasing the number of reconstructed point sources composing an object. A larger point source is reconstructed in the area where an object can be partially expressed by low resolution. The point-spread is adjusted corresponding to the spatial frequency of an object. The effectiveness of the proposed method is confirmed by a computer simulation using two-dimensional images.
