平臺式掃描儀結構

平臺式掃描儀最大的特點是用並行方式對原稿進行掃描輸入。印畫冊掃描圖片的過程是:將原稿放置在原稿平臺上或夾在原稿片夾當中,啟動掃描後,掃描光源與原稿做相對運動,

光源照射原稿,每次點亮一條線(一行),印畫冊被照亮的一行圖像的光線到達光學成像器件並且成像在光電轉換器件上。在平臺式掃描儀上,印畫冊常用的光電轉換器件是電荷耦合器件即。

感光器件所以平臺式掃描儀也稱為信號源光線。

半導體感光單元陣列

數碼輸出模數轉換放大整理光電荷中行傳輸寄存器串列模擬輸出構與工作示意圖。

 

CCD感光器件是由一系列並排排列的感光單元用成,每一個CD感光單元都能將照射

在其上的光能轉換成電荷,光照強產生的電荷就多。然後在單位時間內將採集到的電荷傳送到串列輸出電荷寄存器,並以律行方式輸出到放大器電路和模數轉換電路,最後按定的位深輸出二進制數據編碼,表示的是線性CCD,實際上還有平面陣列結構的CCD以及各種色彩(X1等需要註意的就是,平臺式打描儀在高密度值轉換時,還難以達到滾筒掃描儀的解析度及密度值,特別是採集不到透射原稿非常暗的區域內精細色彩的變化
