Originally posted by dcshooter It raises a lot of interesting questions vis a vis using it for camera lenses - can they even be stacked like a traditional lens in order to allow things like zooming,
"Or to get a different focus, engineers could change the size, spacing and orientation of the pillars. It simply means doing the computer calculations and dialling the results into the new design."
My guess is that current technology precludes zooming, as it creates a fixed layer on the quartz crystal. But if they can figure out
how to reconfigure the arrangement of the crystal layer after it's been deposited, it seems theoretically possible to have a zoom
range.
