Abstract
The pyroelectric responses of conventionally poled films of polyvinylidene fluoride to a step input of radiation have been analyzed and shown to be well described by the superposition of two decaying exponentials governed by the thermal and the electrical time constants of the system respectively. The peak response of the pyroelectriccurrent transient was observed to be proportional to both the pyroelectric coefficient d 31 for PVF2 films of 25 μm thickness so that the peak current response curve may be used to evaluate p (T) and d 31.This publication has 22 references indexed in Scilit:
