• Moire tomography
• Shadowing
• Flow filed's visualization and diagnosis

In this paper, some issues about moire tomography and shadowing in visualizing and diagnosing flow fields are summed up and studied both theoretically and experimentally. These two optical methods are compared on two aspects: the structural visualization and parameter diagnosis for flow fields. Based on which, the feasibility of integrating moire tomography and shadowing in visualizing and diagnosing flow fields is proposed, and the experimental setup is established. Besides, flame flow fields are chosen as practical examples for experiment. The experimental results manifest that integrating moire tomography and shadowing may be one of the reasonable and feasible means for structural visualization and parameter diagnosis of complex flow fields.
