The scanner acquires the image by irradiating the light onto the picture or document to be scanned. After the light is reflected, it is received by the photosensitive element -- CCD (Charge Coupled Device) or CIS(Contact Image Sensor). Due to the different c...

Working Principle of Scanner: Currently, the working principle of desktop scanner is divided into two types: CCD and CIS. CIS products work like fax machines. They have no lens components, and use light emitting diodes as light sources and diode photosensitive elements. Because of its simple and compact structure, the volume can be made very small. The thickness of CIS products is usually less than half that of CCD products. However, CIS devices have no lens imaging part, so the depth of fiel...

DLP is the abbreviation of "DigitalLightProcessing", i.e. digital light processing. That is to say, the image signal should be processed digitally before the light is projected. It is based on the DigitalMicromirrorDevice (DMD) developed by TI (Texas Instruments) company to display the visual digital information. Specifically, DLP projection technology uses DMD as the main processing element to realize the digital optical processing.

DMD chip is an extremely ac...
