Abstract

The planar electrical capacitance tomography (ECT) is a non-destructive evaluation technology (NDE) for imaging 2D/3D permittivity distribution using capacitance measurements between electrodes on a co-planar surface. At present, the sensitivity field distribution uniformity of the planar array sensor is poor, and the image reconstruction quality in the central region is not high. In this letter, a honeycomb-structured sensor with a central and 60-degree rotational symmetry is proposed to improve the uniformity of the sensitive field and enhance the sensitivity in the central region so as to improve the imaging performance.

基于新型平面阵列电容传感器的三维电容层析成像

平面电容层析成像（ECT）是一种无损评价技术（NDE），利用共面表面上电极之间的电容测量来成像二维/三维介电常数分布。目前，平面阵列传感器的灵敏度场分布均匀性较差，中心区域的图像重建质量不高。本文提出了一种中心60度旋转对称的蜂巢状结构传感器，以改善敏感场的均匀性，提高中心区域的灵敏度，从而提高成像性能。
