Abstract
A digitized display system providing a three dimensional image utilizing a display including a multi-frequency sensitive material and a spatial light modulator with individual controllable elements. The spatial light modulator can be a deformable mirror device.
Claims23
A digitized video system for displaying a three dimensional image comprising:
- (a) a three dimensional display including at least one material responding to two energy beams of different characteristics to produce a different energy where said beams intersect and located along two paths;
- (b) a spatial light modulator having a plurality of controllable elements arranged in an array, at least two of said controllable elements being individually controllable between a first state to provide portions of one of said energy beams and a second state not to provide said portions of said one energy beam along one of said paths;
- and
- (c) the other of said energy beams located along the other of said paths to simultaneously intersect a plurality of said portions of said one energy beam.

Method of displaying a three dimensional image comprising the steps of:
- (a) intersecting a three dimensional display with two energy beams of different characteristics including a material producing a different energy where said beams intersect;
- and
- (b) individually and simultaneously controlling at least two elements of an array between a first state to provide a portion of one of said energy beams and a second state not to provide a portion of said one energy beams.
A digitized video system for displaying a three dimensional image comprising:
- (a) a three dimensional display including at least one material responding to two energy beams, a first and a second, of different characteristics to produce a different energy where said beams intersect and located along two optical paths;
- (b) said first energy beam along one of said paths substantially instantaneously irradiating a plane in said three dimensional display;
- and
- (c) a spatial light modulator having a plurality of controllable elements arranged in an array, each of said controllable elements being individually controllable between a first state to provide a portion of said second of said energy beams along the other of said paths to intersect said plane at a predetermined point, and a second state not to provide a portion of said second energy beam,

Method of displaying a three dimensional image comprising the steps of:
- (a) intersecting a three dimensional display with first and second energy beams of different characteristics including a material producing a different energy where said beams intersect;
- (b) defining a plane in said three dimensional display with said first energy beam;
- and
- (c) individually and simultaneously controlling at least two elements of an array between a first state to provide a portion of said second of said energy beams to intersect said plane at a predetermined point, and a second state not to provide said portion of said second of said energy beams.
