FIELD: physics.
SUBSTANCE: invention refers to fluorescing or phosphorescing print check and detection on sheets fed to printing press for securities printing. Luminescent sensor device contains set of subunits, optical sensitive elements, at that each subunit contains ultra-violet lighters for sample illumination, digital camera system containing front element, mirror assembly tracking light radiated from the specified sample to front element of digital camera system; and digital signal processor providing processing of signals, generated by the specified front element of digital camera system. Thus fluorescing or phosphorescing print check and detection system on security sheets contains luminescent sensor device.
EFFECT: improved control quality.
