Abstract

Scientists are using advanced infrared radiation (IR) imaging tools for treatment of pyroelectricity in terms of a change in net dipole moment emerged in moder times. Detector elements made of lead strontium titanate (PST) or barium strontium titanate (BST) are commonly used. The devices operate at room temperatures above the Curie level and an applied electric field induces the pyroelectric effect. Applications exist in areas such as fire fighting, law enforcement and border patrol, land mine detection and facial recognition.
