Abstract

Reconstructions with complex flow fields and limited-projections are two main serious problems that are often encountered in practical OCT cases. While moire tomography has its inherent advantages, such as low mechanical stability demand, to be applied in these complex flow fields. But due to the complex style in its formulation, it is not used as widely as general OCT methods. A proof is given to get an equation which explicit expresses the relationship between moire tomography and general CT methods. A Bayesian maximum a posteriori (MAP) approach is used to reconstruct fields with limited-projections. Based on these works, Numerical experiments are proposed to reconstruct simulated fields with ART and MAP approaches separately.
