Abstract

Thin-film pyroelectric effect detectors provide a simple means of measuring thermal properties of solid samples. The present work reports a time-delay theoretical model of thin-film pyroelectric detection which enables the recovery of thermal diffusivity and thermal conductivity information from the impulse response of the pyroelectric system.
