With novel reconstruction algorithms we attempt to compensate for polarization distortions that arise as light propagates through the catheter. This enables improved imaging of tissue birefringence and provides a complementary contrast mechanism especially for collagen. Imaging of collagen is of high relevance for intracoronary imaging as well as in a range of other endoscopic applications.
