·Provide User ManualUnveiling 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.
