Density-encoded line integral convolution: polarisation optical axis tractography using centroidal Voronoi tessellation

Visualising complex polarimetry optical axis fields is challenging. We introduce density-encoded line integral convolution (DELIC), a novel approach that builds on the classic line integral convolution algorithm by incorporating the principles of centroidal Voronoi tessellation, enabling clearer and more interpretable representations of complex optical axis fields.

Depth-resolved polarisation sensitive optical coherence tomography reveals the complex microanatomical response of cartilage to compression

Conventional methods for analysing cartilage microstructure under mechanical loading are largely destructive. In this work, we evaluate the efficacy of using depth-resolved polarisation sensitive optical coherence tomography (PS-OCT) to study the cartilage morphological response to compression. We show that depth-resolved PS-OCT reveals the microstructure of cartilage under load, and it can do so non-destructively, opening significant possibilities for enhanced clinical assessment of cartilage health by detecting deviance from normal load-bearing behaviour.
