ABSTRACT:
A thermal imaging device comprising a pyroelectric layer having on one major surface an array of interconnected electrodes forming an entrance face, and on the opposite major surface an array of discrete electrodes connected to electrical circuitry formed on a semiconductive substrate. Between the entrance faces of individual detector elements in a network of further electrodes of high thermal conductance which provides a high degree of thermal isolation for the detector elements and prevents significant thermal cross-talk between adjacent detector elements.
