Abstract

This work describes a wide-field imaging Mueller polarimetric system optimized for operation in the VIS and NIR ranges. It makes use of two fast switching compensators with optimal values of retardance that are oriented to a discrete set of orientations. The acquisition of 16 raw intensity images is done in a few seconds, which allows the determination of the complete Mueller matrix of a sample in the backscattering configuration at a speed compatible with in-vivo applications. Mueller matrix NIR imaging of polarization properties unveils quantitative information from deeper parts of the tissue than in systems using VIS radiation, making it an interesting and promising tool for non-invasive biomedical diagnostics.
