• Theoretical and experimental investigations of the thermal transient phenomenon are described on pyroelectric elements on which a light pulse is projected. The transient distribution of pyroelectric elements is calculated as a function of time and space, and discussed for the case of the pyroelectric current. Samples of lead zirconate titanate ceramics (P.Z.T.) and triglycine sulfate (T.G.S.) are used, and these samples are freely suspended or mounted on heat sinks in the experiments. The pyroelectric current follows exactly the incident light pulse in the case of homogeneous spontaneous polarization, but not in the case of inhomogeneous polarization. The mechanism of fast response for pyroelectric detectors is fairly well explained by the thermal diffusion process, and it is shown that the transient response is not diffusion process, and it is shown that the transient response is not affected by the heat sink. These results provides useful data for designing pyroelectric detectors and pyroelectric thermal image devices.
