Abstract

Раскрытый сканер для обнаружения времени затухания света, испускаемого люминесцентным материалом, имеет блок управления, выполненный с возможностью адаптации тока возбуждения или значения напряжения возбуждения, подачи питания на его источник света для соответствующей адаптации интенсивности возбуждающего света, подаваемого к люминесцентному материалу, так что его высокочувствительный оптический датчик может надежно измерять свет люминесценции, испускаемый в ответ на возбуждающий свет, и, таким образом, точно определять соответствующее значение времени затухания.
