    • The invention relates to a device for determining a distribution of charges stored in an element (2) made from a dielectric, said device comprising: an electrode (22) that emits a pulse capable of generating an acoustic wave by displacement of said charges stored in said element (2), said emitter electrode being connected to a generator of said pulse (33), and a receiver electrode (15) connected to said element (2) and equipped with a sensor (16) capable of detecting said acoustic wave and of converting it to an electrical signal, so as to determine the distribution of the charges stored in said element (2) from said electrical signal. According to the invention, the emitter electrode (22) is an electrode with no contact with said element (2) storing said charges, capable of transmitting said pulse to said element (2) through a dielectric that separates said emitter electrode (22) from said element (2), via a line effect.
    • 本发明涉及一种用于确定存储在由电介质制成的元件(2)中的电荷分布的装置,所述装置包括:电极(22),其发射能够通过所存储的所述电荷的位移产生声波的脉冲 所述元件(2),所述发射极连接到所述脉冲(33)的发生器,以及连接到所述元件(2)并具有能够检测所述声波的传感器(16)的接收器电极(15),以及 将其转换为电信号,以便从所述电信号确定存储在所述元件(2)中的电荷的分布。 根据本发明,发射电极(22)是与所述元件(2)没有接触的电极,所述元件(2)存储所述电荷,能够通过使所述发射电极(22)与所述发射极(22)分离的电介质将所述脉冲发射到所述元件 所述元件(2)通过线条效应。
