PROBLEM TO BE SOLVED: To provide a simple restructuring device for a stereoscopic image of a three- dimensional space distribution of a powder in a fluid and for a space distribution of the powder, by which a short continuous phenomenon such as a space movement of a powder can be followed, of which a processing time is short and the amount of a record medium is little. SOLUTION: This device is composed of a projection meansαfor introducing parallel rays each generated from a plurality of positions to a region to be visualized in which a powder is located and transmitting them through the region, a projection image processing meansβfor taking a photograph of a projection image projected by the projection meansαto image-process it, a stereoscopic image construction meansγof a three-dimensional space distribution, for determining a powder concentration distribution of the powder at arbitrary coordinates as a function of the components of projection coordinates to restructure it as for whole region to be visualized, based on a plurality of data each obtained by the projection image processing meansβat the same time, and a construction meansδof a powder traveling speed distribution, which carries out the stereoscopic image construction meansγat two consecutive times to represent each cross correlation of the powder space distributions of the two consecutive times by a distribution of vector values. |
