是一種光電轉換式圖像傳感器。
電荷耦合器件(Charge-Coupled Device,CCD)是一種利用電荷存儲和轉移原理工作的半導體圖像傳感器,主要用于光電信號轉換和傳輸。其核心工作原理和特點如下:
光電轉換與電荷存儲 CCD表面由大量微小的光敏單元(像素)組成,每個像素包含一個光電二極管和一個與之相鄰的電荷存儲區域(勢阱)。當光線照射到像素上時,光子被半導體材料吸收,産生電子-空穴對(光生電荷)。在施加的偏置電壓作用下,這些光生電荷(通常是電子)會被收集并存儲在對應的勢阱中。存儲電荷的數量與入射光的強度成正比。
電荷耦合與轉移 CCD的關鍵特性在于其獨特的電荷轉移機制。像素之間通過緊密排列的電極(栅極)分隔和控制。通過按特定時序向這些電極施加一系列相位變化的電壓脈沖(時鐘脈沖),可以改變電極下方半導體表面的電勢分布。這種電勢變化使得相鄰勢阱的深度發生改變,從而驅動存儲的電荷包從一個像素(勢阱)定向、順序地“耦合”轉移到下一個像素,就像接力傳遞一樣。電荷最終被傳送到輸出端的讀出電路。
信號輸出 電荷包被轉移到輸出端的檢測放大器(通常是一個浮置擴散放大器)。該放大器将電荷量轉換為成比例的電壓信號。這個模拟電壓信號隨後被放大并經過模數轉換(ADC),最終形成數字圖像數據。
