摘　　要：提出了用递归直接二元搜索算法（ＤＢＳ）设计二元位相计算全息图的新方法，分析了ＤＢＳ型位相计算全息图的设计原理，计算机模拟定量地分析恢复象的质量和衍射效率，分析结果表明该位相计算全息图恢复象质量较好、衍射效率高，在光电技术。A new technology for synthesizing binary phase computer-generated hologram(PCGH) by direct binary search(DBS) algorithm is presented. The principle of design DBS PCGH is analysed. The reconstruction quality and diffraction efficiencies are analysed in terms of computer analogue. The results show that the DBS PCGH resulted in substantially well reconstruction quality and high reconstruction efficiencies,and its applications exist in these areas such as optoelectronics technology and optical information processing etc.
