Examples

  1. Design and realization of photographing the color - coding rainbow hologram
    色编码彩虹全息图拍摄实验的设计与实现
  2. For the anticounterfeiting of printings ( such as certificate ) , the existent many ways ( such as rainbow holograms ) are not available as the need for special use : anti - distortion and anti - copy . basing in the double - random - phase transform , this article puts forward a new way that two - dimensional bar code is used as anticounterfeiting label with anti - printing ? scanning and anti - damage properties . the major job are : ( 1 ) . basing in the ascii codes , numerals and alphabets are encoded and subsequently transformed into two - value bar code matrix figure . later , using amplitude - based double - random - phase transform , the enciphered gray scale figure is formed . by computer simulation ( 4f system ) and printing as well as scanning ( 20 times ) , we get the result that the gray scale figure with little miscoding rate ( 0 . 0026 ) by “ matrix expanding way ”
    本文主要开展了以下三项研究工作: ( 1 ) .用自定义编码方案,将数字和字母( ascii码)转换成二值条码图;对该图形进行振幅型双随机相位加密变换,得到原信息的加密灰度图;通过4f光学系统计算机模拟和打印-扫描实验,证明本文提出的“矩阵扩展法”灰度图具有较小的误码率,对于20次打印-扫描实验,误码率不大于0 . 0026 。
