    图像传感器

    图像传感器是将穿过物体或从物体反射的光波或电磁辐射转换成构成图像的信息的设备。图像传感器由数以千计的超小光敏单元组成,这些光敏单元捕捉光线、识别颜色并将其转换成数字信号。

    图像传感器的类型

    市场上有两种主要类型的传感器,它们是CCD传感器和CMOS传感器。

    • CCD传感器的每个光敏电池都是模拟设备。当光线照射到芯片上时,它作为小电荷保留在每个光敏电池中。最靠近(一个或多个)输出放大器的像素行中的电荷被放大并输出,然后每一行像素将其电荷移动到更靠近放大器的一行,填充最靠近放大器的空行。然后重复此过程,直到所有像素行的电荷都被放大并输出。
    • CMOS传感器的结构不同于CCD传感器。与CCD的几个放大器相比,CMOS图像传感器为每个像素都提供一个放大器。这导致捕获光子的区域要小于CCD,但此问题已通过在每个光电二极管前使用微透镜来克服,该微透镜将原本会击中放大器并且不会被检测到的光聚焦到光电二极管中。与CCD传感器相比,CMOS传感器可能具有更少的组件、使用更少的功率和/或提供更快的读出速度。它们也不太容易受到静电放电的影响。

    图像传感器的应用
