Design on the measurement and control of electronics imaging system

The electrostatic imaging technology can be used to obtain target electrostatic image by detecting the electrostatic field around the target. The electrostatic fields around the target are inducted by using detection electrodes of the electronics imaging system to get the target information; the fixed-frequency switch measurement method is adopted for electric fields signal measuring, the synchronous measurement and filter are used according to the practical situation to ensure the high performance of the measurement module; the control module is the key part of the electronics imaging system, signal conditioning module and PXI system are designed to process data acquisition and detection units adjustment of the electronics imaging system. The test results in laboratory indicated that the designed measurement and control module can be used to realize the electric field signal measuring, data acquisition and control, and it provides the basis for the electrostatic imaging technology application.
