| 摘 要： | 相位的计算在二维傅里叶变换等光学计算中有着很重要的作用,在G-S算法等相位恢复算法中更是有着较多的应用.提出了一种全新的相位叠加方案,除了器件本身的光电转换特性外,不需要外加非光学的辅助单元,用全光的方式实现了相位的线性叠加.通过对该计算单元原理和基本构架进行理论分析和计算机仿真,证明了方案的可行性.设计的计算单元既可...

| Abstract: | Calculation of phase plays a very important role in optical Fourier transform and it also has lots of applications in phase retrieval algorithm and the G-S algorithm,etc.A new phase overlay scheme is presented,which does not require additional non-optical auxiliary unit,achieving the function in pure optical way.The theoretical analysis and computational simulation of the basic framework principles are made to prove the feasibility of the program.This scheme can be used as a phase calculating unit in optical computing,and also be used as an optical beam connector which can keep the phase information. |
