RECONSTRUCTION OF THREE-DIMENSIONAL DENSITY DISTRIBUTION FROM THE LIMITED PROJECTION IMAGES WITH GENETIC ALGORITHM
SINOPSIS
Measurement of three-dimensional density distributions in a transient unstable stratified flow is important for the safety analysis on the advanced-type nuclear power plant. Three-dimensional density distribution can be reconstructed using computer tomography techniques from interferogram images. However, in the transient experiment, only two or four interferogram images from different angles can be taken. Conventional tomography techniques have a low accuracy with few interferogram images, because the information of the projection is not enough for the reconstruction. In this study, a new three-dimensional reconstruction technique was proposed. In this technique, the genetic algorithm was introduced to reconstruct the whole field from a few interferogram images.
