DEVICE FOR DETECTION OF PROTECTIVE MARKS IN THE CONTROL OF AUTHENTICITY securities and documents (optional)

摘要

The utility model relates to means for the control of authenticity of the objects (IO) 3. An apparatus comprising: lighting means, arranged in the form of an LED oscillator radiation and infrared radiation source which is operatively in a pulsed mode EUT 3; photodetector system comprising: a photodetector generated by irradiation, the respective surface portions 3 EUT radiation, formed as a linear array of radiation detectors; a photodetector associated with a processing unit, which is authentication control means 3 based on the IO processing, digitizing and comparing the values ​​of said characteristic parameters of the generated radiation, for the photodetector, with reference values ​​that are stored in the memory unit. The generator of electromagnetic radiation is organized as two modules which are spaced relative to one another to irradiate predetermined zones EUT 3. The LEDs 1 in each of said modules structurally formed as linear arrays of LEDs 1, each of which has a length less than the width of said predetermined zone EUT 3. a linear photodetector array comprises photodiodes 4 and structurally organized as two modules, each of which is located opposite to a corresponding module generates ora radiation from the opposite side of the test object 3. As specified values ​​of the characteristic parameters of the generated luminescence radiation (i.e., response) detected by a photodetector, using radiation and luminescence decay characteristic by the specification, placement topology fluorescent security marks are provided on the EUT 3. variants . 2 bp f-ly, 6 ZP f ly-4-yl.
