Popis:	Estimation of space charge distributions in laminates is difficult owing to the heterogeneity of their structure which induces signal contributions. In this paper, a simple correction procedure is presented in order to remove heterogeneity-induced signal contributions when using the pressure-wave-propagation (PWP) or pulsed-electro-acoustic (PEA) methods. It is then possible to analyse the signal as if it was delivered by a uniform material. Experiments are shown to validate the correction produre.
