Claims11
For use in electronic color imaging apparatus of the type having a multicolor light source directed toward an imaging station in which color photosensitive imaging medium is disposed, an improved electro-optic modulator comprising:
- (a) a panel of electro-optic material of the type transformable from an isotropic state to a birefringent state in response to application of an electric field;
- (b) addressable electrode means disposed on said panel in a regular pattern defining a plurality of separately-activatable pixel portions within said panel;
- and
- (c) a plurality of filter means respectively of different colors and coupled to different individual pixel portions of said panel.
For use in electronic color imaging apparatus of the type having a multicolor light source directed toward an imaging zone, an improved electro-optic modulator comprising:
- (a) a light valve array, including a panel of electro-optic material, transformable between light blocking and a light passing states in response to application of an electric field;
- (b) addressable electrode means disposed on said panel in a regular pattern defining a plurality of separately-activatable pixel portions of said array;
- and
- (c) a plurality of filter means respectively of different colors and integral with different respective pixel portions of said array.
In electronic color apparatus of the type having an exposure station and a multicolor light source directed toward said exposure station, an improved light valve device for controlling passage of light from said source to color photosensitive medium located at said exposure station in accordance with an electrical signal containing information of a color image to be reproduced, said device comprising:
- (a) an electro-optic modulator including:
- (1) a panel of electro-optic material of the type transformable from an isotropic state to a birefringent state in response to application of an electric field, (2) addressable electrode means disposed on said panel in a regular pattern defining a plurality of separately-activatable pixel portions within said panel and (3) a plurality of filter means respectively of different colors and coupled to different individual pixel portions of said panel;
- and
- (b) means for addressing said electrode means in accordance with such electrical signal.
In electronic color apparatus of the type having an imaging station and a multicolor light source directed toward said imaging station, an improved light valve device controlling passage of light from said source to said imaging station in accordance with an electrical image, said device comprising:
- (a) an electro-optic modulator including:
- (1) a light valve array comprising a panel of electro-optic material and transformable between light blocking and light passing states in response to application of an electric field, (2) addressable electrode means disposed on said panel in a regular pattern defining a plurality of separately-activatable pixel portions of said array and (3) a plurality of filter means respectively of different colors and coupled to different respective pixel portions of said array;
- and
- (b) means for addressing said electrode means in accordance with such electrical signal.
