Abstract
Recent advances in integrated photoelasticity have opened the possibility of determining tomographically arbitrary three-dimensional stress fields. Since photoelastic tomography is based on experimental measurement of the characteristic parameters, the dependence of these parameters on the stress distribution on a light ray is considered in detail. The possibility of determining certain integrals of the stress components is analyzed, and the linear approximation of integrated photoelasticity has been rigorously treated.
