Distributed system for producing holographic stereograms on-demand from various types of source material
View Patent ↗A distributed system for producing holographic stereograms (holograms). A data acquisition station is typically remote from image processing, printing, and replicating stations. The data acquisition station is designed to maximize customer convenience, and may be the customer's own personal computer. The data acquisition station is further designed to accept a wide variety of source data and to perform whatever processing is required to deliver image data to the image processing station in an acceptable format. The data acquisition station further has processing capability to display preview images, which may be assembled by programming executing at the data acquisition station or downloaded from a server.
1. A system comprising:
an image processing station having an image processor operable to generate hogel data for separate regions on a hologram based on image data received from a remote location; and
a printing station in data communication with the image processing station and comprising:
a spatial light modulator for receiving the hogel data from the image processor and for displaying holographic object images, and
a printer for exposing a recording medium with the holographic object images to produce a hologram.
2. The system of claim 1 wherein the image data further comprises at least one of: data from a still camera, data from a video camera, data from a 2D scanner, data from a 3D scanner, or one or more graphics data files.
3. The system of claim 1 further comprising:
a data acquisition station having a data acquisition processor operable to receive source image data and transmit the image data to the image processing station.
4. The system of claim 3 wherein at least two of the data acquisition station, the image processing station, or the printing station are coupled to each other via a communications network.
5. The system of claim 1 wherein the image processing station is further operable to prepare and store hogel data for multiple holographic object images for subsequent delivery to the printing station.
6. The system of claim 1 wherein the image processing station is further operable to prepare and transmit hogel data for a single holographic object image to the printing station.
7. The system of claim 1 wherein the image processing station is remote from the printing station.
8. The system of claim 1 wherein the printer further comprises a plurality of lasers, and wherein a first one of the plurality of lasers has a wavelength different from a second one of the plurality of lasers.
9. The system of claim 1 wherein the printer further comprises at least one of a pulsed laser a continuous wave laser.
10. The system of claim 1 further comprising a replicating station for producing hologram copies from a master hologram.
11. The system of claim 1 , wherein the spatial light modulator comprises a liquid crystal display.
12. A method comprising:
receiving, at an image processing station, image data from a remote location;
processing the image data to generate hogel data for separate regions on a hologram; and
transmitting the hogel data to a printing station, the printing station comprising:
a spatial light modulator for receiving the hogel data from the image processor and for displaying holographic object images, and
a printer for exposing a recording medium with the holographic object images to produce a hologram.
13. The method of claim 12 wherein the image data further comprises at least one of: data from a still camera, data from a video camera, data from a 2D scanner, data from a 3D scanner, one or more graphics data files.
14. The method of claim 12 further comprising:
acquiring the image data and transmitting it to the image processing station.
15. The method of claim 12 further comprising:
coupling the image processing station and the printing station to each other via a communications network.
16. The method of claim 12 further comprising:
preparing and storing hogel data for multiple holographic object images for subsequent delivery to the printing station.
17. The method of claim 12 further comprising:
preparing and transmitting hogel data for a single holographic object image to the printing station.
18. The method of claim 12 wherein the image processing station is remote from the printing station.
19. The method of claim 12 wherein the printer further comprises a plurality of lasers, and wherein a first one of the plurality of lasers has a wavelength different from a second one of the plurality of lasers.
20. The method of claim 12 wherein the printer further comprises at least one of a pulsed laser or a continuous wave laser.
21. The method of claim 12 further comprising
replicating at least one copy of the hologram produced by the printer.
22. The method of claim 12 , wherein the spatial light modulator comprises a liquid crystal display.
