Abstract
A camera arrangement includes a camera, a light source, and a light-guide which are in an inside region separated from an outside region by a window. The camera and the light source are pointed at the window. The light-guide is between the camera and the window and between the light source and the window. The light-guide couples light incident to the window from the outside region towards a portion of the camera. The light-guide couples light from the light source into the window which is reflected at the interface between the window and the outside region and couples the reflected light towards another portion of the camera. The camera records an image indicative of the incident light from the outside region through the light-guide and records an intensity of the reflected light from the light source through the light-guide.
