The Study and Experiment of ERT Imaging System

Abstract

The Electrical Resistance Tomography (ERT) is a new technology developed in recent years. Because of the characteristics as simple structure, low cost and non-invasive, the ERT has already application in geophysics, physical geography, mineral detection et al.in this paper, the ERT is used to detect the damage of the remote carbon fiber felt with wireless sensing technology. In experiment, the wireless technology is used to avoid the noise and the introduction of the long wires, which realized the remote detection; the Improved Newton -- Raphson algorithm is used to achieve the detective imaging, which had good results.
