Abstract
A selective light transmitting and receiving system for the reduction of glare and unwanted light. The selective light system includes a light source, a first polarized filter adapted to polarize light emanating from the light source in a first polarization orientation, a second polarized filter adapted to perform polarized filtering of received light in a second polarization orientation, and a light receiving device adapted to receive the filtered light. The selective light system may be incorporated into a vehicle system, a roadway system, a camera or video system, a microscope system, a night vision device, a hard hat lighting system, and a stage lighting system.
Claims57
A vehicle glare reduction system, comprising:
- a light source;
- a first polarized filter adapted to polarize light emanating from said light source in a first orientation, wherein said first orientation is substantially horizontal or vertical;
- and
- a second polarized filter situated in front of a driver viewing area and adapted to perform polarize filtering of incoming light in a second orientation substantially orthogonal to said first orientation.
A roadway glare reduction system, comprising:
- a road;
- and
- a plurality of polarized filter panels situated along said road and configured to polarize light emanating from the Sun and/or other light sources.
A roadway glare reduction system, comprising:
- a road;
- and
- a plurality of roadway lights for lighting said road, wherein said roadway lights respectively comprise polarized filters adapted to polarize light emanating from respective said roadway lights.
A camera or video system, comprising:
- a light source;
- a first polarized filter configured to polarize light emanating from said light source;
- a second polarized filter adapted to perform polarized filtering on a received light;
- and
- a light sensitive device adapted to receive said filtered light.
A microscope system, comprising:
- a light source;
- a first polarized filter configured to polarize light emanating from said light source;
- a second polarized filter adapted to perform polarized filtering on a received light;
- and
- an objective lens adapted to receive said filtered light.
A night vision device, comprising:
- an infrared light source;
- a first polarized filter configured to polarize infrared light emanating from said infrared light source;
- a second polarized filter adapted to perform polarized filtering on a received infrared light;
- and
- an infrared light sensitive device adapted to receive said filtered light.
A hard hat lighting system comprising:
- a hard hat;
- a light source attached to said hard hat;
- and
- a first polarized filter adapted to polarize light emanating from said light source.
A stage lighting system, comprising:
- a stage light source;
- and
- a first polarized filter adapted to polarize light emanating from said stage light source.
