Digital photoelasticity – A comprehensive review
TLDR
This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.Abstract:
Digital photoelasticity has rapidly progressed in the last few years and has matured into an industry-friendly technique. This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques. The overall objective is to provide enough information and guidance to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.read more

Comparison of High-Speed Polarization Imaging Methods for Biological Tissues
TL;DR: In this article , the authors applied a polarization filter array and high-speed camera to the imaging of biological tissues during large, dynamic deformations at 7000 frames per second, and compared the results with previous measurements of similar specimens using a rotating polarizer imaging system.

Texture analysis integrated to infrared light sources for identifying high fringe concentrations in digital photoelasticity
Hermes A. Fandiño Toro,Juan C. Briñez de León,Alejandro Restrepo Martínez,John William Branch Bedoya +3 more
TL;DR: In this paper, the authors used a circular polariscope to observe a birefringent disk under diametral compression to identify regions with high fringe densities in digital photoelasticity images, which represent a limitation for unwrap the phase in specific zones of the stress map.

Fourier fringe analysis: the two-dimensional phase unwrapping problem.
TL;DR: A new phase unwrapping algorithm is described that uses local phase information to mask out those parts of the field that cause inconsistencies in the unwraps and can produce an approximately correct unwrapped.

Towards full field automated photoelastic analysis of complex components
Eann A. Patterson,Z F Wang +1 more
TL;DR: The design of a automated system for photoelastic analysis of complex components and the potential of the system for providing detailed data over the full field of view is demonstrated by the analysis of a slice from a model of a bolt.

Demodulation of a single interferogram by use of a two-dimensional regularized phase-tracking technique
TL;DR: A two-dimensional regularized phase-tracking technique that is capable of demodulating a single fringe pattern with either open or closed fringes and gives the detected phase continuously so that no further unwrapping is needed over the detectedphase.
