Can non-destructive space charge measurement techniques have fallout in other fields?

For more than 20 years, non-destructive space charge distribution measurement techniques have been successfully used to study electrical phenomena in insulators and dielectrics. Where other experimental techniques would require various hypotheses, they give directly spatial information. The implementation is carried out by producing a perturbation within the sample which may involve thermal diffusion, elastic wave propagation or electrical stress. A recent physical study of these methods gives a vision that offers new types of applications. In this paper the question of complex geometry sample and of free charge detection is considered.
