My prototype 3D display shows that 3D objects can be projected in space in color without moving parts by using a scalable high-resolution screen, 10 micrometer pixels, that combines up to 100 views. The patented high-resolution screen uses coherent optical fiber bundles to combine the images of many spatial light modulators together. The straightforward modular approach makes it easy to: scale the screen up; adjust light output and change 2D and 3D resolution. Depending on the computer used refresh rates go from 0.1 up to real-time. The volume of the apparatus is comparable to an ordinary TV set. The paper will include concepts, theory, experiments, proof of concept and configurations for different uses. The flexibility of the system allows you to make curved 3D screens, live size 3D screens and even the possibility to reproduce the 'Princess Leia it's a hologram' of Star Wars effect.
The development of the Office Holoprinter makes progress and people become interested. Discussing the possibilities one of the major concerns is the image quality. How does the quality of an one-step holograms compare with that of a traditional hologram? Can holograms made with different recording techniques be compared and if so by which means. This paper will discuss several parameters to compare different holograms and how to determine the quality.
We will report on the status of the development of the OFFICE HOLOPRINTERTM. Last year we showed that we were able to make one-step holograms. This year we will show a new approach to quality one-step holograms and explain the practical and theoretical principles. This paper will also include new possibilities for holoprinter input.
We present our progress towards the development of an Office Holoprinter. Extra attention will be given to total concept layout and individual steps. We will evaluate the different project parts and discuss problems and possible solutions.
We will report on the status of the development of the OFFICE HOLOPRINTERTM. We are investigating a new active matrix color LCD spatial light modulator driven by our Silicon Graphics workstation with TRACESTM software. Discussed will be the results and experiments. Also different kinds of HOE's in combination with the LCD screen together with a variety of one-step recording possibilities will be discussed. The final part of the paper will include DHL's concept for the holoprinter as a whole and which parts are being improved to arrive at a professional multi-purpose office holoprinter. This includes tests of software and approaches to make 3D images.
We are developing a prototype of an office holoprinter. We are investigating a new active matrix LCD spatial light modulator in combination with a dry developable photopolymer to be used in our office holoprinter. We will present our latest results in full-color multiple photo generated holograms. These are made using 3 different color laserlines. We will expand on the theory behind the principle recording geometry, to include circular track recording.
A theoretical analysis will be presented on how to generate computer images, so each recorded perspective presents the appropriate view to the viewer in the final hologram. To further improve our results we developed an optical registration system on each slite for controlled projection of the perspective views. We produced a full-color image-plane computer generated and a full-color image-plane "stereogram" (circular track) image using 3 different color laser lines. We propose to name the Computer generated holograms and stereograms from now on Multiple Photo Generated Holograms (MPGH). We are testing a very high resolution active matrix black-and-white LCD as interface between computer and printer.
