Paper Abstract
Cancerous and precancerous growths often exhibit changes in scattering, and therefore depolarization, as well as collagen breakdown, causing changes in birefringent effects. Simple difference of linear polarization imaging is unable to represent anisotropic effects like birefringence, and Mueller polarimetry is time-consuming and difficult to implement clinically. This work presents a dual-polarization endoscope to collect co- and cross-polarized images for each of two polarization states, and further incorporates narrow band detection to increase vascular contrast, particularly vascular remodeling present in diseased tissue, and provide depth sensitivity. The endoscope was shown to be sensitive to both isotropic and anisotropic materials in phantom and in vivo experiments.
