  • Electrostatic induction probe arrangement using several probes
    Patent number: 4760342
    Abstract: An electrostatic induction probe arrangement using several probes. The probe electrodes and the screen electrodes surrounding them are fitted to the end faces of a substrate arrangement, and the conducting paths leading to the preamplifiers are arranged in several parallel planes, perpendicular to the end face, in such a way that the signal-conducting paths connected to the probe electrodes are essentially screened by the screen-conducting paths connected to the screen electrodes.
