At the 5mof on 2011-10-20, Alex presented her research on holography and
scratch holograms. A scratch hologram is as follows:
We (Dany, Alex, and I) got together and made a scratch hologram in the
space last wednesday in a spare piece of acrylic we found. (Just a
simple letter "V" as the site suggests.) We also learned how to properly
use the laser engraver without burning it out.
We want to make a simple one of these with the laser engraver soon, then
make a piece of software which can take 3D files and output
corresponding laser art files for "scratch" holograms. I have some ideas
about how to do that, but would like to make a few simple hand-drawn /
-calculated but laser-made holograms first.
The current idea is that we're gonna be around for fab wednesdays,
because it seems like a good fit with 3D fabrication. I thought I would
let you all know; hopefully we can make something better together than
we could apart.
