3D Technology Labs is developing a true 3D display, where
the "image" actually exists in three dimensional space.
Unlike typical computer screens, viewers can walk around the display
and view the image from all sides.
The display works by using multiple infrared lasers to sweep
through a glass cube specially treated with rare earth ions, which
are excited by absorbing the laser engergy. When the ions return
to the unexcited state, they give off light at a particular voxel.
The images is redrawn 30 to 60 times a second, resulting in a
Dr. Downing will be talking about this technology for viewing
true, moving 3D images in a small glass cube. The talk will discuss
various chemical species and material systems in which this phenomenon
works (and doesn't work), system integration and architecture
issues, features of this type of volumetric display (vs say rotating
ones), and application areas for this emerging technology.
Dr. Downing received her B.S., in Mechanical Engineering from
Carnegie Mellon University. She received both an M.S. and Ph.D.,
in Mechanical Engineering at Stanford University.
