Abstract
A thermal imaging device includes detector pixels A, B, C provided by a pyroelectric layer 1 arranged between electrode structures 3 and 4. A photoconductive layer 7 is provided between the electrode structure 5 and a further electrode structure 9. The device also includes an illumination source 11 for illuminating the photoconductive layer 7 for enabling pyroelectric charge developed by the detector pixels A, B, C to be optically addressed via the electrode structure 9. Optical addressing of the detector pixels obviates the need for solid state switching connections to each pixel, providing an imaging device readily capable of large scale fabrication.
