Unveiling the Operation of Scanning Modules

Imagine that the scanning module is like a super eye, and its workflow is like this:

Firstly, it uses a light source (such as a laser or LED light) to illuminate the item you want to scan, and this light source will be selected according to different scanning needs. This process is like turning on a flashlight in the dark, illuminating the road ahead.

When light touches an object, it will reflect back and be captured by the lens in the scanning module. This lens is like a small magnifying glass, focusing the reflected light into a clear image. The quality of an image depends on the quality of the lens and its focal length setting.

Next, a magical component called an image sensor appeared. It's like a translator, converting images into electrical signals. This sensor may be a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), both of which are highly skilled at converting optical signals into electrical signals.

The electrical signal is then sent to the decoding chip for further processing. The decoding chip is like a sound engineer, it amplifies the electrical signal, removes noise, and then converts it into a digital signal. In this way, the data becomes both clear and reliable.

These digital signals are then sent to the main control board, which acts as the brain of the scanning module, responsible for processing data while controlling other parts of the module. The main control board can be connected to computers or other devices through various interfaces to transmit processed data.

Before the data is transmitted, the main control board will also undergo a "physical examination", which is data verification. It will use various methods such as parity check or CRC to ensure the accuracy of data. If any errors are found, they will be corrected immediately.

Finally, the data that has been filtered and processed layer by layer can be outputted. They are usually transmitted to computers or other devices through interfaces for further analysis, identification, storage, or other applications.

Simply put, the scanning module converts the image of an object into a digital signal through optical equipment, then performs a series of processing and applications, and finally outputs the result. This process can be controlled and controlled through computers or other devices, making scanning work more automated and intelligent.
