Abstract
A pyroelectric sensor having an active regulation for maximizing pyroelectric sensor sensitivity is disclosed. The pyroelectric sensor comprises a ferroelectric transducer, and a regulator. The ferroelectric transducer may either be a homogenous ferroelectric transducer, a compositionally graded ferroelectric transducer, or an externally graded ferroelectric transducer. The regulator may either be an excitation regulator or a temperature regulator. A method for regulating the excitation or the temperature of a pyroelectric sensor for maximizing sensitivity of the pyroelectric sensor is also disclosed.
