摘要：
The invention relates to a device for reading the quantities of electrical charges borne by a dielectric sheet using a probe scanning the charged surface of the sheet and connected to an electronic circuit adapted to measure the quantities of charges induced on said probe. This electronic circuit comprises an operational transimpedance amplifier and an analog integrator reset to zero periodically by suitable circuitry.
