ABSTRACT:
A grated thin-film surface forms a plurality of successive narrow silvered panels which are oriented to provide a composite and linear mirror. The thin film is mounted against a support whose inward face is a congruent replica of the inside upper section of a vehicle windshield, or sandwiched between the plies of such a support. The reflective surface is covered with a layer of liquid crystal of which the opacity can be electrically adjusted. The plane of each silvered panel is defined by a first transversal angle in reference to the horizon, and by a longitudinal angle in reference with the slant of the underlying inward face section of the support and windshield.
