Abstract

Дифракционно-оптично въздействащият елемент включва прекъснат метализиран пласт и/или частично метални пластове, и/или зони с метални пластове в различни равнини, които представляват целенасочено нанесено кодиране на информация. Устройството е снабдено с капацитивно работещо сканиращо устройство, което се състои от множество, разположени един до друг, предавателни електроди и един, разположен успоредно на този ред, приемателен електрод. Сканиращото устройство се монтира в машина за обработка надокументи така, че оптичните или механичните сензори, намиращи се в обикновените машини за обработка на документи, да активират контролното устройство. Енергията от активирания в даден момент предавателен електрод, при положение, че е налице електрическа проводимост между този предавателен електроди приемателния електрод, се свързва капацитивно. При липса на електрически проводящ елемент не се предава енергията между активирания предавателен електрод и приемателния електрод. Сигналите на приемателния електрод се преобразуват в съответен вид на сигнала. Видът на сигнала зависи от структурата на метализирания пласт на дифракционно-оптично въздействащия елемент. Анализираща електроника, поставена след приемателния електрод, сравнява вида на сигнала от проверявания обект със съответни опорнисигнали.
