Hardcopy holography provides a method for displaying autostereo three-dimensional information in a manageable two-dimensional form. Current optical technologies require process intensive holographic procedures to optically record the many stereo views required for full parallax holographic images. The One-step Full Parallax Full color image as it names implies, produces via a onestep optical pixel printer, image plane reflection holograms that have both vertical and horizontal parallax and are full color or RGB color based.
Original data starts out as a CAD file describing the model or content as polygon structures with surface descriptors and illumination positions.
To produce the many thousands
of rendered images required for an image (current image is 8 x 10" with
1mm pixels: 183 rows by 220 columns or 40,260 pixels), we have developed
a high speed "just in time" renderer, and a holographic optical printer
that images holographic pixels at .9 sec intervals.
As such this image as rendered on Brenhiede BB-Pan plates took 12 hours to print.
This set of images are some of the views of the Honda JVX concept car as imaged in a full parallax onestep hologram
Future research in the development of One-step Full Parallax printers will include: holographic optical elements (HOE), format increase to A3 size prints, and pixel size reduction. SPI is developing tools for visualizing medical data from magnetic resonance imaging (MRI) and other applications of three-dimensional imaging techniques.
