Induced polar materials for intense radiation monitoring

Abstract

Theoretical and experimental researches on the electric potential spatial distribution in thin crystal plates of zinc selenide and quartz, presented in this paper, is a constituent part of a common approach elaborated for a study of the polar states induced by inhomogeneous heating in a wide class of materials including those not belonging to the polar crystallographic classes. Construction original principles of a new class of the transmission-type power pyroelectric sensors with a maximum attainable upper limit of the dynamic range for an intense radiation monitoring in a wide region of IR spectrum are developed.
