Paper Abstract

Imaging spectropolarimetry is an informative technique that can be useful as a tool to detect and analyze cancerous tissues. However, to fit clinical standards, imaging spectropolarimeters must be fast, drift-free, and without any recurrent calibration, which is not the case for most imaging spectropolarimeters based on nematic liquid crystal phase modulators. Here, we present an instrument based on a novel architecture of differential liquid crystal variable retarders cells. A complete spectropolarimeter was built using this architecture and is now part of a clinical study at the dermatology department of the Strasbourg University Hospital.
