电荷耦合器件(Charge-Coupled Device,CCD)是一种利用电荷存储和转移原理工作的半导体图像传感器,主要用于光电信号转换和传输。其核心工作原理和特点如下:
光电转换与电荷存储 CCD表面由大量微小的光敏单元(像素)组成,每个像素包含一个光电二极管和一个与之相邻的电荷存储区域(势阱)。当光线照射到像素上时,光子被半导体材料吸收,产生电子-空穴对(光生电荷)。在施加的偏置电压作用下,这些光生电荷(通常是电子)会被收集并存储在对应的势阱中。存储电荷的数量与入射光的强度成正比。
电荷耦合与转移 CCD的关键特性在于其独特的电荷转移机制。像素之间通过紧密排列的电极(栅极)分隔和控制。通过按特定时序向这些电极施加一系列相位变化的电压脉冲(时钟脉冲),可以改变电极下方半导体表面的电势分布。这种电势变化使得相邻势阱的深度发生改变,从而驱动存储的电荷包从一个像素(势阱)定向、顺序地“耦合”转移到下一个像素,就像接力传递一样。电荷最终被传送到输出端的读出电路。
信号输出 电荷包被转移到输出端的检测放大器(通常是一个浮置扩散放大器)。该放大器将电荷量转换为成比例的电压信号。这个模拟电压信号随后被放大并经过模数转换(ADC),最终形成数字图像数据。
