Abstract
The copolymer VDF-TrFE (VF2/C2F3H, derived from polyvinylidene fluorid e with 30 mol% trifluoroethylene) used in a pyroelectric mode to devel op IR focal plane arrays for civilian applications is compared to the barium strontium titanate BST used in a dielectric bolometer approach to implement a low cost IR imager. Comparison of the respective techno logies, of the stability of both systems, and of their performances is presented. In spite of the better performance of the BST, the VDF-TrF E approach presents the advantages of monolithic integration, which ma kes it easier to implement, and lower cost.
