<p>The inside rear-view mirrors presently used in private automobiles provide the driver with a view through the rear window, but also a view on the image of things placed on the rear shelf which is specularly reflected from the rear window. This image draws away the attention of a driver what, in traffic, could be dangerous. The invention suppresses specular reflections from rear window and offers the driver a clear view through it. This is achieved by setting a vertical polarizer (8) in front of a reflecting coating (10) in the optical system (3) of a rear-view mirror. Vertically polarized portion of light (13) carrying the image of the traffic behind the automobile passes through optical system (3) and reaches the eyes of the driver (19). Substantially horizontally polarized specularly reflected light (26) carrying image of the things (21) placed on the rear shelf (22) is absorbed by optical system (3).</p> |
