A simple isolation table I use is illustrated in figure 5. It consists of three components, a piece of carpet (or soft foam), a small 12" diameter inner tube, and a 12" x 12" x 1/8” thick ferrous metal plate.

The carpet can be substituted with a piece of thick cloth (towel) or 1/8” thick soft foam. The inner tube is filled with just enough air for it to be filled but still be soft and easy to squeeze. The ferrous metal plate needs to be thick enough to support itself and a few lightweight components without flexing or bending. The plate needs to be a ferrous metal so that a magnet will stick to it.
Paint the steel table top flat black. This will help cut down on unwanted laser reflection and will improve the quality of the holograms.
Where to Shoot
You need to find a place that can be made dark and quiet, with little vibration. Since our table and equipment is portable, this should help finding a suitable location easier.
When exposing a holographic plate (shooting the hologram(s)), do not have music playing in the background or fans running. These can generate vibrations that may prevent the hologram from recording properly on the holographic plate.
