摘要

Abstract: For the examination of mixing processes in turbulent flows a system based on a high-speed solid state camera has been implemented, which allows for the quasi-simultaneous acquisition of sequences of tomography data in flows. In these data, velocity fields are being determined by 3D least squares matching. The paper shows the hardware configuration for the flow tomography data sequence acquisition and the algorithm for 3D least squares matching with additional constraints for tracking in tomography voxel data. !14
