Abstract

A method for single-write holographic imaging involves determining a layout of a plurality of holographic images on a substrate, the plurality of holographic images including at least a first holographic image having a first parameter set and a second holographic image having a second parameter set, inputting the parameter sets into a database and controlling an imaging apparatus to image the first and second holographic images on the substrate in a single session to create an integrated holographic pattern.

Claims (43)

1. A method for single-write holographic imaging, said method comprising the steps of:

determining a layout of a plurality of holographic images on a substrate, said plurality of holographic images including at least a first holographic image having a first parameter set and a second holographic image having a second parameter set, said second parameter set being different from said first parameter set;

inputting said first parameter set and said second parameter set into a database; and

controlling an imaging apparatus having an object beam and a reference beam to image said first and second holographic images on said substrate in a single session to create an integrated holographic pattern;

wherein said first parameter set includes parameters determining, the angle of incidence and rotation of said object beam and said reference beam with respect to said substrate, and the spacing of the point of interference of said object beam and said reference beam for each pixel in said first hologram image, and second parameter set includes parameters determining the angle of incidence and rotation of said object beam and said reference beam with respect to said substrate, and the spacing of the point of interference of said object beam and said reference beam for each pixel in said second hologram image;

wherein said first holographic image and said second holographic image are printed onto said substrate sequentially;

wherein said step of controlling an imaging apparatus to image said first and second holographic images on said substrate includes imaging said first holographic image on a discrete portion of said substrate and imaging said second holographic image on an entirety of substantially said same discrete portion of said substrate as said first holographic image, in order to produce a combination holographic image.

2. The method according to claim 1 , wherein:

said single session includes imaging said first and second holographic images on said substrate without manually manipulating elements of said imaging apparatus between imaging of said first holographic image and said second holographic image.

3. The method according to claim 2 , wherein:

said holographic images include a plurality of holographic optical elements.

4. The method according to claim 1 , wherein:

said imaging apparatus is a split-beam holographic imaging apparatus.

5. A method for single-write holographic imaging, said method comprising the steps of:

providing a holographic imaging apparatus capable of imaging a plurality of holographic images on a substrate;

controlling said apparatus via an integrated computer network, said computer network having manual input capabilities;

determining a layout of an integrated image, said integrated image having holographic and non-holographic elements;

determining at least a first holographic image having a first parameter set and a second holographic imaging having a second parameter set, said second parameter set being different from said first parameter set;

wherein said computer network controls said holographic imaging apparatus so as to imprint said first and second different holographic images on said substrate sequentially in a single-write process with an object beam and a reference beam, said single-write process being accomplished without manual manipulation of imaging elements of said holographic imaging apparatus,

wherein said holographic imaging apparatus imprints said first and said second holographic images in combination of said non-holographic elements.

6. The method according to claim 5 , wherein:

each of said holographic images themselves are comprised of one or more holographic optical elements;

wherein a holographic parameter set of each of said holographic optical elements include one or more of angle of a reference beam and an object beam, rotation of said reference beam and object beam and the spacing of a point of interference of said reference beam and object beam from said substrate.

7. The method according to claim 6 , wherein:

said holographic imaging apparatus is a split-beam holographic imaging apparatus.

8. The method according to claim 6 , wherein:

said step of controlling said holographic imaging apparatus so as to imprint said first and second different holographic images on said substrate includes imaging said first holographic image on a discrete portion of said substrate and imaging said second holographic image on substantially said same discrete portion of said substrate as said first holographic image.

9. A method of creating a dispersed white light optical effect using holographic imaging, said method comprising the steps of:

providing a single imaging laser as part of a holographic imaging apparatus;

arranging said holographic imaging apparatus to produce an object beam and a reference beam so as to be capable of imaging holographic images on a substrate;

imaging a first holographic image having a first parameter set upon a discrete portion of said substrate; and

imaging a second holographic image having a second parameter set upon said substrate after said first holographic image is imprinted, said imaging of said second holographic image occurring on an entirety of said substantially same discrete portion of said substrate as said first holographic image;

wherein said first and second different holographic images are imprinted on said substrate in a single-write process to produce a combination holographic image, said single-write process being accomplished without manual manipulation of imaging elements of said holographic imaging apparatus.

10. The method according to claim 9 , wherein:

each of said holographic images is comprised of a plurality of holographic optical elements each having a parameter set.

11. The method according to claim 10 , wherein:

said parameter set includes an angle of incidence of said reference beam on said substrate.

12. The method according to claim 11 , wherein:

said angle of incidence is substantially low such that a dispersed white-light design is viewable.

13. The method according to claim 10 , wherein:

said parameter set includes one or more of rotation of said reference beam and an object beam and the spacing of a point of interference of said reference beam and object beam from said substrate.

14. The method according to claim 9 , wherein:

said first parameter set of said first holographic image is different from said second parameter set of said second holographic image.
