The main purpose of the bar code in the modern world is the unique identification of the product, service, or any of their
features, so personal and stationary barcode scanners so widely used.
One of the important parameters of bar code scanners is their reliability, accuracy of the barcode recognition, response
time and performance.
Nowadays, the most popular personal barcode scanners contain a mechanical part, which extremely impairs the
reliability indices. Group of SUAI engineers has proposed bar code scanner based on laser beam acoustic deflection
effect in crystals [RU patent No 156009 issued 4/16/2015]
Through the use of an acousto-optic deflector element in barcode scanner described by a group of engineers SUAI, it can
be implemented in the manual form factor, and the stationary form factor of a barcode scanner.
Being a wave electronic device, an acousto-optic element in the composition of the acousto-optic barcode scanner allows
you to clearly establish a mathematical link between the encoded function of the bar code with the accepted input
photodetector intensities function that allows you to speak about the great probability of a bar code clear definition.
This paper provides a description of the issued patent, the description of the principles of operation based on the
mathematical analysis, a description of the layout of the implemented scanner.
