Abstract
A thermal imaging detector including a layer of heat-sensitive material which includes a doped ferroelectric material exhibiting a pronounced rise in resistance with temperature in the vicinity of the ferroelectric/paraelectric transition, a multiplexing circuit, a thermally insulating thin-film microstructure, and a matrix segmentation at the level of the material of the heat-sensitive layer, so as to define heat-sensitive picture elements.
