摘要
分析了基于球面波载波的计算全息透镜的设计方法 ,给出了载波参数应满足的条件和抽样间距、抽样点数与设计参数 (焦距、孔径 )之间的关系 ,讨论了实际数字化全息制作设备对输出全息透镜参数的影响并给出了参考解决方法。
Computer generated holographic lens with spherical carrier wave is analyzed, and the criterion for selecting carrier wave parameter is presented. The relationship between sampling period, sampling numbers and holographic lens's parameter, such as focal length and aperture is determined. The influence of digital image output equipment on holographic lens is discussed and the referenced solving method is given.
