电阻层析成像技术最优激励与测量模式的研究
Research on Optimal Excitation and Measurement Mode of Electrical Resistance Tomography
摘要
Abstract
Excitation and measurement mode of Electrical Resistance Tomography (ERT) system would determine the sensitivity, information quantity and noise immunity of the test field.In this paper, a 16-electrode ERT system was cited to conduct a research on 8 excitation modes and 2 measurement modes by numerical analysis.The number of independent measurement, is opotential line distribution were compared as well as the amplitude and sensitivity characteristics of measured voltage.Based on an overall consideration of various factors, Mode 7 and the reference measurement mode are considered to be the best choices.关键词
