The phase shift between a pyroelectric voltage and a temperature oscillation wave in the measurement of induce pyroelectric coefficient using dynamic method is studied. Experiment results show that there is a 90° phase shift between a pyroelectric voltage and a temperature wave for intrinsic pyroelectrics, while there is no phase shift for induced pyroelectrics. Theory calculations are developed based on AC and DC equivalent circuit to elucidate the phenomena. It has been suggested that different phase shifts are attributed to the capacitance dependence on the temperature of specimens.
