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.   Near-field beam pattern measurement of qualification model of ALMA band 8 (385-500 GHz) cartridge receiver 期刊论文  OAI收割 EXPERIMENTAL ASTRONOMY, 2009, 卷号: 24, 期号: 1-3, 页码: 89-107 作者:  Naruse, Masato;  Ito, Tetsuya;  Sekimoto, Yutaro;  Toba, Hiroyuki;  Satou, Naohisa 收藏  |  浏览/下载：18/0  |  提交时间：2011/12/08 Near-field beam pattern measurements  SIS receiver  Physical optics simulation   螺线管传输并聚焦高能质子束的数值模拟研究 学位论文  OAI收割 作者:  张忠亚   |  收藏  |  浏览/下载：42/0  |  提交时间：2018/12/26 强场激光物理  high field laser physics  螺线管  solenoid  PIC数值模拟  PIC numerical simulation  质子束  proton beam  离子光学  ion optics  像差  aberration
