Three-dimensional computed tomography from interferometric measurements within a narrow cone of views

Abstract

A theory is presented and tested for recovering a fluid property from measurements of its projections. Viewing comes as small as 10° are evaluated, and the only assumption is that the property is space limited. The results of applying the theory to numerical and actual interferograms of a spherical discontinuity of refractive index are presented. The theory was developed to test the practicality and limits of using three-dimensional computed tomography to process optical diagnostic data for internal fluid dynamics.
