The study is concerned with developing a fast 3D imaging method for sparks and so using digital camera from a few projections. The point of this method is rapidly to reconstruct 3D images form a few projections, using the Singular Value Decompositions and the sampling model object.The first, we investigated a new algorithm by using the SVD.The results of computer simulation experiments based on the algorithm were good. We obtained good conditions between reconstructing parameters. The second, we tried to design hardware and software interface with a digital camera, and aucceeded in acquisition of emission images from flames. The third, we experimented with the reconstruction algorithm, and succeeded in 3D imaging for flames. The 3D images reconstructed were good. Several experiments made it obvious that there is a possibility that the reconstruction method will come into practical use.
