What is an optical scanner?
As the name suggests, an optical scanner is an input device that can scan an image, code, text or object with a beam of light and convert the digital signal into a two-dimensional digital file. These files are then sent to computers and fax machines for further processing. The most popular type of optical scanner is the flatbed scanner. Optical scanners have a wide range of applications, including reading customized response forms, creating automatic data fields, and recording fingerprints.
Historical background of optical scanners
Optical scanner technology was developed by Willard Boyle and George Smith in 1969. Since then, it has developed significantly and has become an essential tool in various fields such as document management, security and industrial automation.
How do optical scanners work?
Optical scanners are based on charge-coupled devices (CCDs), which are composed of photosensitive receptors. It is through these receptors that the incident light is converted into electrical signals, and then the conversion work of the optical scanner is completed. CCD capacitors can respond to up to 70% of the incident light, while film can only respond to about 2%.
But light cannot distinguish between text and graphics when passing through an optical scanner. All our scanned content will be converted into bitmap images. We cannot edit the scanned text directly. Therefore, to solve this problem, the optical character recognition system converts handwritten, typed or printed text image information into a scanned file that we can edit according to standard code characters, which is now also used in many optical scanners.
Components and connections of optical scanners
In order to ensure the consistency of imaging quality, optical scanners usually come with proprietary software. These accessories are linked to computer devices through the use of external input/output channels (via serial bus, small computer system interface, FireWire and wireless adapter, etc.), so that they can be used successfully.
