Abstract
The complementary field method has been applied to interferometric tomographic reconstruction of high speed aerodynamic flows involving a shock. It is based on the reconstruction of the complementary field, which is the difference between the object field to be reconstructed and its estimate. The method is iterative and incorporates a priori information. This study demonstrates advantages of the method in alleviating the difficiencies associated with computational reconstructors and measured data. Substantial reconstruction improvement is obtained, especially near a shock when its position is utilized as a priori information. Under the test conditions, convergence is rapid.
