A novel technique is proposed for measuring an instantaneous spatial reaction zone profile of turbulent premixed flames. The technique is realized by combining multi-lens-camera photography with computer tomography. The technique is applied to measure a spatial profile of PET resin powder particles in a jet to verify its accuracy and validity. The results show that the 3D spatial mapping of the particles reconstructed with multi-dimensional data agrees well with the original picture, resulting in enough accuracy of the proposed optical diagnostics. In this report, error factors, for example aberrations of lens, positions of pictures and numbers of pictures used for CT reconstruction, are experimentally examined.
