摘要
Technologies enabling low-dissipation designs for uncooled array IR sensors are offered. The technique involves the etching of special buffer layers from under a 1-mu m membrane followed by deposition of an IR-sensitive film and electrode structure. The electrical and physical properties of plumbum-zirconate-titanate (PZT), barium titanate (BaTiO3), tetraaminodiphenyl (TADPh), polyvinylidene fluoride (PVDF) pyroelectric films are compared. A circuit for sensing pyroelectric signals in a CCD is considered.
