A prototype polarization camera.
The schematic of a prototype polarization camera is shown below. The incident light is linearly polarized parallel to the scattering plane (the source-tissue-camera plane). An optical flat enforces a uniform skin/glass interface for reflection of glare away from the camera. The polarized scattered light and the multiply diffusely scattered light reach the camera after passing through a linear polarizer that can be oriented parallel or perpendicular to the scattering plane.
