ABSTRACT:
The invention provides a thermal camera tube having a reticulated pyroelectric target, that is to say a target having a plurality of separate pyroelectric elements arranged in rows and columns and separated by channels. Each of the separate elements has the shape of a cube the vertical sides of which are inclined so that, except for those in one outer column and one outer row, on two of its sides the top of each element overhangs the base of an adjacent element in the same row and the base on an adjacent element in the same column so that the overhanging surface of the element is exposed to radiation in the region of channels separating it from the aforementioned adjacent elements.
