Abstract
An imaging system includes a projector, a camera and a filter set of polarization filters. The projector is to project light onto a surface. The camera is to capture light reflected from the surface. The filter set is to remove light of a first polarization from the projected light and to remove light of a non-first polarization from the reflected light so that the camera detects only reflected light having the first polarization.
