DEVICE FOR DETERMINING A CHARGE DISTRIBUTION IN A DIELECTRIC ELEMENT

摘要

The invention relates, in particular, to a system for transmitting at least one electric pulse for an apparatus for determining a distribution of charges contained in the thickness of an item (2) made of a dielectric material, said transmission system including a transmitter electrode (1) for transmitting at least one pulse and a generator (3) of said pulse. The system is notable in that said electrode is formed by a transmission line (1) which is substantially level in relation to the item (2) to be analyzed and which includes impedance matching means to keep said impedance substantially constant along said transmission line in the passband of said pulse.
