Abstract

In this paper, a method of multidirectional moire deflectometry is presented and used to obtain multidirectional moire patterns of the asymmetric flow field in hypersonic (M = 10.29) shock tunnel. At the same time, a 3-D reconstructive method of asymmetric flow field is presented also which is based on the integration of the moire deflective angle and double-cubic many-knot interpolating splines; it is used to calculate the 3-D density distribution of the asymmetric flow field.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
