EXPERIMENTAL STUDIES OF A POLARIZED HEADLIGHT SYSTEM. PT V VISIBLE DISTANCES OBTAINED WITH SOME LAMINATED AND TEMPERED WINDSHIELDS

IN FULL-SCALE FIELD EXPERIMENTS VISIBILITY DISTANCES WERE MEASURED FOR 15 LAMINATED AND 11 TOUGHENED WINDSHIELDS. THE RESULTS SHOW THAT LAMINATED WINDSHIELDS CONSTITUTE A FAIRLY HOMOGENOUS GROUP WHICH IS ACCEPTABLE TOGETHER WITH A POLARIZED HEADLIGHT SYSTEM. THE TOUGHENED WINDSHIELDS ON THE OTHER HAND DIFFER VERY MUCH. SOME MAKES ARE ACCEPTABLE WITH A POLARIZED HEADLIGHT SYSTEM WHILE MOST ARE NOT. THE ANGLE OF INCLINATION OF A LAMINATED WINDSHIELD HAD SERIOUS DEPOLARIZATION EFFECTS ON VISIBILITY DISTANCES ONLY WHEN THE ANGLE TO THE VERTICAL WAS LARGER THAN 60 DEG. THIS WAS TESTED IN A SIMULATOR. /AUTHOR/
