FIELD: images forming devices.
SUBSTANCE: invention relates to the technical field of finance, and more particularly to devices and systems for producing a banknote image. Banknote image acquisition system comprises fiber laser (1), fiber beam splitter (2), fiber collimator (3), laser beam expander (4), matrix (5) of lithium niobate intensity modulator, signal generator (6), signal amplifier (7), polarization beam splitter (8), quarter-wave plate (9), lens group (11), forming images, line of photosensitive microcircuits (12), image information processing module (13), and image registration module (14).
EFFECT: increase in the resolution of the details of the banknote image without the need to increase the number of units of light-sensitive chips per unit length of the linear matrix image sensor.
