提出了一种计算机生成柱面全息图的快速计算方法。该计算方法是基于波在谱域和圆柱坐标系中的传播，这在其他方面类似于直角坐标系中平面波的角谱。计算只需要两次FFT运算，因此速度快得多。介绍了计算方法的理论背景、采样条件和模拟结果。对所产生的柱面全息图在不同视角和平面上的再现性进行了测试。
A fast calculation method for computer generation of cylindrical holograms is proposed. The calculation method is based on wave propagation in spectral domain and in cylindrical co-ordinates, which is otherwise similar to the angular spectrum of plane waves in cartesian co-ordinates. The calculation requires only two FFT operations and hence is much faster. The theoretical background of the calculation method, sampling conditions and simulation results are presented. The generated cylindrical hologram has been tested for reconstruction in different view angles and also in plane surfaces.
