Another cool holographic thought
Posted: Thu May 27, 2004 9:25 am
I thought of this idea this morning and I am very excited to try it. Feel free to try it yourself if you want as it would be a very exciting first hologram which would be very efficient and very stable in its configuration.
First take a piece of ordinary mirror the size or large then your plate. Place it on a layer of about 10 paper towels. Put on safety glasses and gloves. Take a metal rod and push down into one place on the mirror, just off center until the mirror breaks. Do not disturb the broken pieces. Then take your holograhic plate and lay it gently on the broken mirror emulsion side up. Let this stand for at least one hour. Expose with laser coming in from one of the sides. Do not forget to mask off the leading edge of the holographic film with black tape (not shown) so as not to get internal reflections.
The effect when it is hangin on a wall will be very nice with gratings going in different direction because the paper towels held the broken mirror in a deformed state with depression at point of break. In my case, if I can get it to replay broadband it will look like a broken mirror on the wall.
I may try to "prop" up the plate so it will be a couple of inches from the broken mirror pieces.
So many ideas so little time!!!
Peace and have fun!
