We have successfully integrated a thermally insulating silica aerogel thin film into a new uncooled monolithic thin film infrared (IR) imaging device. We have calculated noise equivalent temperature differences of 0.04–0.10°C from a variety of PbxZryTi1−yO3 (PZT) and PbxLa1−xZryTi1−yO3 (PLZT) pyroelectric imaging elements in these monolithic structures. The low thermal conductivity of the aerogel...
