Abstract Scope Optical ptychography has gained significant interest in recent years, due to its ability to provide quantitative phase images and improve the spatial resolution of images obtained using low numerical aperture lenses. Here we exploit the quantitative nature of the complex exit surface waves recovered using ptychography to separate the in-plane stress components for samples subject to mechanical loading. The technique, termed `photoelastic ptychography', is first benchmarked against a sample with a known stress-induced birefringence - a diametrically compressed disc. Having established proof-of-principle, we then extend this work and apply it to examining biological samples. The formalism developed to describe the birefringent properties of the sample is constructed within the framework of Jones calculus. Future work will focus on extending our approach to three dimensions and time-resolved stress measurements.
