  • Patent number: 5657161
    Abstract: A system is provided for eliminating light reflections within the cockpit of a vehicle having a canopy with a reflective interior surface. A first polarizing filter overlies a lighted display, enabling an occupant of the vehicle viewing the display to read information presented thereon. A second polarizing filter oriented 90.degree. out of phase with respect to the first filter is interposed in the cockpit in a line of sight between the occupant and reflections off the reflective interior surface of the canopy which initiate at the display thereby preventing the reflections from being seen by the occupant without affecting the ability of the occupant to see the lighted display. Preferably, the polarizing filters lie in substantially parallel spaced planes. Also, each polarizing filter may be mounted for movement between active and inactive positions.
