Moiré Deflection Tomography: Application in Visualization and Diagnosis of Compressible Flow Fields

This book presents a comprehensive exploration of moiré tomography and its application to structural visualization and key-parameter diagnosis in high-temperature complex flow fields. The content is organized around five main themes:

1. Theory – Establishment of the refractive-index model essential for applying moiré tomography to flow-field diagnostics, and investigation of the physical mechanisms underlying refractive-index gradient variations.

2. Experiment – Analysis of experimental challenges and their impact on results, with explanations and validations based on scalar diffraction theory.

3. Information extraction – Techniques for phase-information extraction, spectrum analysis, phase retrieval, deflection-angle acquisition, and refractive-index reconstruction.

4. Key-parameter measurement – Retrieval of critical flow-field parameters, including temperature and electron number density.

5. Method extensions – Preliminary studies on extending moiré tomography to atmospheric applications.
