Description

The basic idea of nondestructive testing is that a sample is characterised by its response to a certain kind of excitation. The excitation may be an electric or elastic field with a time pattern described by a step, a pulse, or a sine wave type. The field can be applied locally to characterise the area around a certain sample spot. A raster scan image is then performed by measuring many spots one after the other.
