Abstract
In this article, we present a novel algorithm for digital analysis of the photoelastic patterns to provide direct birefringence measurements of fibres based on photoelastic intensities distribution. The validity of the introduced mathematical scheme is confirmed by comparing the calculated birefringence profile to the profile measured using the two-beam Pluta polarising interference microscope. The proposed method is applied to patterns of high (and low) birefringence gradients. This algorithm, with the aid of the single-frame computed tomography, is used to measure the 3D birefringence profile of necking in polymeric fibres. Also, a dynamic study of the mechanical behaviour of polymeric fibres is given. Digital photoelastic and two-beam interference patterns are included for illustration.
