Abstract
A complementary field method has been devised for 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 in nature and incorporates a priori information. This study demonstrates advantages of the method in alleviating the deficiencies 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 of the method is rapid.
