How's Laser Barcode Scanner work?

Rakinda laser barcode scanner mainly uses the laser principle to work. Laser is different from other light, it has the characteristics of directional light, great energy and high brightness, which is called "the most accurate ruler" by many scientists, and it can shine straight in a certain direction.

Ordinary light sources emit different photons, so they are very disunited and will each run in different directions. The photons emitted by a laser have the same characteristics, so they move at the same pace, gather in a group and are extremely energetic. Since the discovery of laser, it has been used by human beings in various places and is a good helper for people.

 

Lasers are used in a wide range of applications, and laser scanners are one of them. The scanner is equipped with a laser diode inside that emits a laser beam, which is reflected when it hits a mirror that moves back and forth and is refracted through the scanner's reading window to the surface of the barcode. Finally, the laser is reflected by the barcode or the air and returns to the reading window, where it is converted into an electrical signal through a photoelectric converter. This electrical signal is finally translated by the scanner's decoding software to derive the information.

 

The laser scanner is mainly used for non-contact scanning, even if the barcode is not very clear, it can be well discerned; its speed is the fastest among all scanner types; the chance of scanning out wrong information is extremely low, and it is a widely used scanner in various industries.
