Разработка поляриметрического датчика для систем идентификации личности

Abstract

Повышение распознающей способности и совершенствование методов защиты Ð´Ð°ÐºÑ‚Ð¸Ð»Ð¾ÑÐºÐ¾Ð¿Ð¸Ñ‡ÐµÑÐºÐ¸Ñ ÑÐºÐ°Ð½ÐµÑ€Ð¾Ð² является одной из Ð°ÐºÑ‚ÑƒÐ°Ð»ÑŒÐ½Ñ‹Ñ Ð·Ð°Ð´Ð°Ñ‡ современности. Цель данной работы - разработка способа повышения защищенности оптоэлектронной системы идентификации отпечатков пальцев. Для повышения защищенности системы идентификации выбраны и теоретически обоснованы методы, основанные на регистрации параметров обратно рассеянного поляризованного излучения, в частности, метод поляризационной визуализации. Разработана методика ÑÐºÑÐ¿ÐµÑ€Ð¸Ð¼ÐµÐ½Ñ‚Ð°Ð»ÑŒÐ½Ñ‹Ñ Ð¸ÑÑÐ»ÐµÐ´Ð¾Ð²Ð°Ð½Ð¸Ð¹, собран измерительный стенд, выполнены исследования на Ð¼Ð¾Ð´ÐµÐ»ÑÑ Ð½Ð°Ñ‚ÑƒÑ€Ð½Ñ‹Ñ Ð±Ð¸Ð¾Ñ‚ÐºÐ°Ð½ÐµÐ¹ и Ð¼Ð¾Ð´ÐµÐ»ÑÑ Ñ„Ð°Ð»ÑŒÑˆÐ¸Ð²Ñ‹Ñ Ð¾Ñ‚Ð¿ÐµÑ‡Ð°Ñ‚ÐºÐ¾Ð² пальцев. Проведенное экспериментальное исследование позволяет говорить о перспективности метода и Ð²Ð¾Ð·Ð¼Ð¾Ð¶Ð½Ð¾ÑÑ‚ÑÑ ÐµÐ³Ð¾ применения при решении задачи повышения защищенности дактилоскопической системы идентификации.
