Author Affiliations +
In order to understand 3D transient flow, it is very essential to apply holographic interferometric tomography. The technique is also advantages in providing nonintrusive measurement capability with reasonable accuracy and spatial resolution. Here, a new computational tomographic algorithm which is termed as Curvilinear Nonlocal Basis Function Method is introduced for reconstruction of flow fields. It is appropriate for reconstruction under various ill-posed conditions involving a limited view angle and an opaque object inside a field with irregular boundaries. The reconstruction technique is tested through computer simulation of experiments as well as a real 3D flow field. The results presented here demonstrate reliable measurement accuracy when the technique is applied for reconstruction of transient 3D flow.
