Abstract

Сензорът се прилага за измерване структурата на линиите поне на частично топлопроводима повърхност (10), за предпочитане пръстов отпечатък. С него сеувеличава точността, тъй като е намалено въздействието на външните фактори. Сензорът има множество сензорни елементи (15), които се нагряват и са в термичен контакт със значителна част от изследваната повърхност. Измерването на температурата или промяна на температурата на всеки от сензорните елементи дава сигнал, съответстващ на топлинната загубав съотношение с подаваната енергия във всеки от тях. Като се нанася полученият сигнал във всеки елемент, се получава сегментирана картина въз основа на разликите в топлинните загуби на отделните сензорни елементи.
