Simulation of Excitation Characteristics in Sensing Field of Electromagnetic Tomography System
摘要
Abstract
Electromagnetic tomography (EMT) has potential value in process measurement. The frontier of electromagnetic tomography system is the sensor array. Owing to the excited signal acting on the sensor array directly, the excited strategy, the excited frequency and amplitude characteristics affect the quality of the information that the detected coil acquired from the object space. Furthermore, it would affect the accuracy of the information post extracted from the object field. To improve the sensitivity of the sensor array on the changes of the object field distribution, upgrade the sensitivity and accuracy of the system and guarantee high precision and high stability of the experimental data, finite element simulation software, COMSOL multiphysics was used, to analyze the excited strategy and the characteristic of the excitation frequency of EMT. And the relationship between the output character with the excited strategy and excited frequency was acquired. Establish the foundation in optimal using of EMT sesor array was established.关键词
