Non-Contact and Self-Calibrated Photopyroelectric Method for Complete Thermal Characterization of Porous Materials
A general theory of a photopyroelectric (PPE) configuration, based on an opaque sample and transparent pyroelectric sensor, backing and coupling fluids is developed. A combined back-front detection investigation, based on a frequency scan of the phase of the PPE signals, followed by a self-normaliza...
