CIS由LEn光源阵列(LEolightsource)、微自聚焦棒状透镜阵列(Rod Lens array)、光电传感器阵列(CMOS image sensor array)及其电路板、保护玻璃、接口、外壳等部分组成。

CIS的组成部分都集中于外壳内，结构紧凑，体积小、重量轻，其主要部件生产需要微制造工艺完成。当CIS工作时，LED光源阵列发出的光线直射到待扫描物体表面(印刷品等)，从其表面反射回的光线经自聚焦棒状透镜阵列聚焦，成像在光电传感器阵列上(一般是MOS器件)，被转化为电荷存储起来。

扫描面不同部位的光强不同，因而不同位置传感器单元(即CS的像素)接收到的光强不一样。每个读取周期每个像素的光照时间(电荷积蓄时间)是一致的，达到积蓄时间后，由移位寄存器控制模拟开关依次打开，将像素的电信号以模拟信号的形式依次输出，从而得到纸币的模拟图像信号。

CIS consists of LEn lightsource array (LEolightsource), micro-self-focusing Rod Lens array (Rod Lens array), photoelectric sensor array (CMOS image sensor array) and its circuit board, protective glass, interface, housing and other parts.

The components of CIS are concentrated in the shell, compact structure, small size and light weight, and the production of its main components requires micro-manufacturing process. When CIS works, the light emitted by the LED light source array is directly directed to the surface of the object to be scanned (printed matter, etc.), and the light reflected back from the surface is focused by the self-focusing rod lens array, and the imaging is converted into a charge and stored on the photoelectric sensor array (generally MOS devices).

The light intensity of different parts of the scanning surface is different, so the light intensity received by different position sensor units (i.e., CS pixels) is not the same. The illumination time (charge accumulation time) of each pixel in each reading cycle is consistent. After the accumulation time is reached, the analog switch controlled by the shift register is turned on successively, and the electrical signal of the pixel is output successively in the form of analog signal, so as to obtain the analog image signal of the banknote.
