Reconstruction the image on video display unit by electromagnetic leakage
视频显示器图像的电磁泄漏重建

Electromagnetic leakage of video display unit becomes the focus of wide interest recently. An image-reconstruction system is presented here using electromagnetic leakage from video display unit. In this system a loop antenna is employed to receive the radiation. After being magnified, A/D transferred, the received data are processed by computer to reconstruct the image. The experiment shows the feasibility and good performance of this system.
