Determination of the characteristic directions of lossless linear optical elements
Hanno Hammer
We show that the problem of finding the primary and secondary characteristic directions of a linear lossless optical element can be reformulated in terms of an eigenvalue problem r…

Application of Sharafutdinov's Ray Transform in Integrated Photoelasticity
H. Hammer, B. Lionheart
We explain the main concepts centered around Sharafutdinov's ray transform, its kernel, and the extent to which it can be inverted. It is shown how the ray transform emerges natura…

Characteristic Parameters in Integrated Photoelasticity: An Application of Poincare's Equivalence Theorem
Hanno Hammer
The Poincare Equivalence Theorem states that any optical element which contains no absorbing components can be replaced by an equivalent optical model which consists of one linear…
