摘要：Superimposition of reproduced rays from sub-holograms is a useful method for view-zone expansion, image-size enlargement, or colorization of electronic-holography. For this superimposition, half- mirrors are preferable because of their size and weight. However, slanted half- mirrors in the ray-axis cause astigmatism in the reproduced images. We analyze this phenomenon and formulated it mathematically. Then, a novel compensation method is proposed by introducing a linear light source with an inverse astigmatism replacing the object sample points. Experimental results show the efficacy of this method.
