  1. 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 ”

    本文主要開展了以下三項研究工作: （ 1 ） .用自定義編碼方案，將數字和字母（ ascii碼）轉換成二值條碼圖;對該圖形進行振幅型雙隨機相位加密變換，得到原信息的加密灰度圖;通過4f光學系統計算機模擬和列印-掃描實驗，證明本文提出的「矩陣擴展法」灰度圖具有較小的誤碼率，對於20次列印-掃描實驗，誤碼率不大於0 . 0026 。
