| 摘要 |
According to one aspect of the invention, a system for controlling light, includes (1) apparatus for responding to incident electromagnetic radiation, including a first medium through which incident electromagnetic radiation may be transmitted; liquid crystal means positioned with respect to said first medium for responding to a characteristic of the incident electromagnetic radiation to cooperate with such first medium to effect refraction of such electromagnetic radiation at an interface of said first medium and said liquid crystal means; and (2) apparatus for filtering a wavelength of light, including a variable polarization rotator means for supplying input light at a prescribed angle of polarization, variable dispersion means for rotating the plane of polarization of such input light an amount that is a function of the wavelength of such input light, and analyzer means for blocking transmission of that light which is output by said variable dispersion means and has a plane of polarization which is crossed relative to the axis of polarization of said analyzer means. The invention also may include a glint reducing device.
