    • An optical scanning module with linear CMOS image sensor (linear CMOSM) applied to scanners or multi-function printers is disclosed. The optical scanning module includes a light source for emitting light, a reflection mirror group, a focus lens group, and a linear CMOS image sensor having at least one linear CMOS image sensor unit and one A/D analog-digital converter. The light source can be a cold cathode fluorescent lamp (CCFL), a Xenon lamp or linear LED. Light emitted from the light source projects onto an object being scanned. Then the light reflected by the object being scanned becomes scanning light, passing through the reflection mirror group and the focus lens group and being focused on the linear CMOS image sensor for being converted into electrical signal. By A/D conversion of the linear CMOS image sensor unit in the linear CMOS image sensor, signal is sent out in USB or LVDS format so as to achieve high scanning speed, low distortion, large depth of focus and convenient transmission.
    • 公开了一种具有应用于扫描仪或多功能打印机的线性CMOS图像传感器(线性CMOSM)的光学扫描模块。 光扫描模块包括用于发光的光源,反射镜组,聚焦透镜组和具有至少一个线性CMOS图像传感器单元和一个A / D模拟数字转换器的线性CMOS图像传感器。 光源可以是冷阴极荧光灯(CCFL),氙灯或线性LED。 从光源发射的光投射到被扫描的物体上。 然后被被扫描物体反射的光成为扫描光,通过反射镜组和聚焦透镜组,并被​​聚焦在线性CMOS图像传感器上,以转换为电信号。 通过线性CMOS图像传感器中的线性CMOS图像传感器单元的A / D转换,以USB或LVDS格式发送信号,以实现高扫描速度,低失真,大焦深和方便的传输。
