Abstract
Integrated photoelsticity is a method for determining stress distribution in photoelastic materials by polaried optical techniques. An important model describes the imaging process is truncated transverse ray transform (TTRT) proposed by Sharafutdinov. In this article, we use this model to fit the reconstruction problem into a TV-L2 minimization scheme and propose a numerical reconstruction method combining algebraic reconstruction technique and augmented Lagrangian method.
