The realizing methods of OAI include geometrical optics method and physical optics method. However  the former has the disadvantage of weak intensity distribution controlling ability  and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized  and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE  light beam propagation distance  and the structure of the beam shaping unit  a method of determining the designing parameters is discussed. Using this method  several illumination modes are realized  and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last  and it is proven to be feasible. 2010 SPIE.   Fine interference fringes formed in high-order harmonic spectra generated by infrared driving laser pulses 期刊论文  OAI收割 phys. rev. a, 2008, 卷号: 78, 期号: 3, 页码: 33841 Xu Han; Xiong Hui; 曾志男; Fu Yuxi; Yao Jinping; 李儒新; 程亚; 徐至展 收藏  |  浏览/下载：1285/223  |  提交时间：2009/09/18 A-center  Argon gas  Driving pulse  Harmonic spectrum  High-order  High-order harmonic generation  Interference fringe pattern  Interference fringes  Phase-matching conditions  Propagation axis
