Hello all, I'm wondering how nutty you have to be about vibration isolation? I have the Holography Handbook, but the thought of a 2000lb sand table was not exactly practical (well, that's the way my DAD saw it :)) Anyhow, I am looking for a small setup for some amateur holograhy (with a pointer). Regards, Robin

For a long time I used 3'X 4' sidewalk tiles for my small experiments. As a matter of fact, you don't need much more than a basement floor (I heard even kitchen table) for single beam reflection holograms, the type where you place the plate on top of your object and illuminate through the plate.
For split beam holograms it becomes much more critical to have vibration isolation. The concrete sidewalk tile with one, two or three (or four?:) inner tubes underneath will suffice in most cases for simple split beam hologhrams with shor texposure times. It will really depend on your location, ie. if you are in an appartment or house with basement, if streetcars go by your home, etc, etc. Good luck and have fun... 24.141.84.254

Hi Robin, to begin with I will recommend you to try out Frank DeFreita's SHOEBOX configuration. If you have success and wish to make splitbeam holograms I will refer to John Myszkowski's experiences. Personally I'v made me a 4'x 8' concrete table with a steel table-top (I'v used 6 innertubes). Well, you can build a smaller one and still make really nice splitbeam holograms. If you are thinking of making transmission Masters and reflection copyes I will recommend you to take a look at Vidar Hegdal's Homepage (you will find the adress on F. DeFreitas's link-page. Vidar have made a lot of very nice holograms, and used the ByPass technics. Have fun under your Green Safe-Light. 130.67.15.242

Thanks for the info, guys. Just today I sent my order for the Shoebox Holography booklet. Can't wait to see it.
