Photopyroelectric thin‐film instrumentation and impulse‐response detection. Part I: A theoretical model

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...

Description
Summary: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.
