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 first applied to measure a spatial profile of a cluster of salt particles to verify its accuracy and validity. The results show that the 3D spatial mapping of salt particles reconstructed with multi-dimensional data agrees well with the original picture, resulting in enough accuracy of the proposed optical diagnostics. Reaction zone profiles of turbulent premixed flames are then reconstructed using the proposed technique. It is shown that ring-like reaction zone profiles are also successfully reconstructed with multi-dimensional data of flame emission in some horizontal sections, indicating extreme usefulness of the proposed technique in analyzing spatial flame structure.
