Design on the electrostatic imaging system

Target electrostatic image can not be obtained through the electrostatic field around target by using general electrostatic detecting probes. Target electrostatic image system is proposed based on detecting probe shielding, which is composed of detector array assembled with local earth-shield detection units, where the electrostatic measurement module possess high sensitivity, together with the control system and image processing module. Test results in laboratory indicated that electrostatic image can be obtained using the electrostatic imaging research system, providing the basis for the electrostatic imaging in future application.
