Reasons for Ambiguity in Retardation Calculations in Phase‐shifting Technique
TL;DR: The atan and atan2 functions are standard features of a high level programming language like Fortran or C, which are used to calculate the inverse tangent functions, and considering that the angle 8 refers to the fast axis of the model produces the following intensity equation.

Photoelastic analysis of stress frozen slices using five-step method
T. Kasimayan,K. Ramesh +1 more
TL;DR: In this paper, stress frozen 3D models are sliced mechanically and the whole field principal stress differences (Isochromatics) and principal stress directions (Isoclinics) are evaluated by capturing only five images using the standard optical arrangements of a conventional polariscope.

Separation of isochromatics and isoclinics phasemaps for the photoelastic technique with use phase shifting and a large number of high precision images
Cristina Almeida Magalhães,Perrin Smith Neto,Pedro Américo Almeida Magalhães Júnior,Clovis Sperb de Barcellos +3 more
TL;DR: In this article, a phase-shifting method was proposed to find new equations for a novel phase shifting method in digital photoelasticity, where only the analyzer is rotated, and the other equations are deduced by applying a new numerical technique instead of the usual algebraic techniques.
