要約(英語): Computed tomography (CT) method has been used for industrial application as well as it has been mainly developed in a medical field. We have investigated the measurement of nonuniform electric field vector distributions in liquid dielectrics using an original method based on electrooptic Kerr effect and CT method. In applying CT method to the reconstruction of the electric field, a principle of CT method has been faithfully observed, which has been one of cause of the error. Specifically, region passing through of the light for measurements was not equal to the reconstructed region and the electric field was reconstructed without consideration of the value of cells outside of the region for reconstruction. So, to solve these problems, we suggested the improved algorithm for reconstruction using the concepts which we called “actual region projection data” and “extension of region for reconstruction”. By a simulation and an experiment, the usefulness of the improved method was studied.
