Design and evaluation of the poleidoscope: A novel digital polariscope
TL;DR: In this article, a polariscope that allows simultaneous capture of multiple images is described, and a prototype instrument is evaluated using both transmission and reflection photoelasticity, offering the potential for real-time data acquisition and processing of high-speed events.

Optical measurement techniques – A push for digitization
TL;DR: This work presents a new digital photoelasticity Reference EPFL-ARTICLE-222716 that combines holographic interferometry and digital image correlation for Fringe projection profilometry with real-time information about the response of the human eye to light.

Study of interaction effects of asymmetric cracks under biaxial loading using digital photoelasticity
A. Vivekanandan,K. Ramesh +1 more
TL;DR: In this article, the authors used the corrected Atluri-Kobayashi multiparameter stress field equation in conjunction with the over-deterministic least squares method to determine the stress intensity factor (SIF) for a single central crack in a cruciform specimen, when the biaxial ratio is increased from 0 to 1, only shielding is observed.

Colour Adaptation in Three Fringe Photoelasticity
TL;DR: In this article, a new methodology to tune the calibration table obtained for a single material to accommodate the tint variation in TFP is proposed for the use of different specimen materials, and the results obtained are compared with the phase shifting technique.

Towards effective phase unwrapping in digital photoelasticity
V Sai Prasad,K.R Madhu,K. Ramesh +2 more
TL;DR: A new method is developed to remove ambiguity in the phase map using isoclinic–isochromatic interaction and a flexible algorithm for phase unwrapping is developed using tiling.
