I've seen a few posts on this forum proposing variations to Pepper's Ghost, I am hoping someone might have some advice for me.
I'm looking to implement the technique in an art installation, the space I have to work with is about 4 x 3 m and has a curved/dome like walls & ceiling,
I plan to adapt the construction of an enclosed structure to best accommodate the particularities of the space (namely its curve) the positioning of the various elements required for the technique, and to minimize the size of the angled 'glass' surface that captures the reflection that the viewer sees.
I have scoured the net for all info I can find regarding this angled 'glass' surface, the various solutions people have used ranging from a low-budget plexi-glass solution, to Eyeliner's patented setup & holo-foil,
Budget-wise I would be happy on settling for something inbetween these two , my own tests with plexi-glass haven't given very effective results - with the audience at close proximity, effectively 'hiding' the edges of plexiglass does not seem very possible.
A very thin surface seems more desirable so I have been trying to find out what the "Eyeliner foil" actually is, since it is patented it is only ever referred to as that. Certain clues in their patent led me to Beam splitter coatings and this company that mentions Pepper's Ghost in relation to their product : Thin Metal Films LTD - Beam Splitter Coatings
I am currently waiting to hear back from them, but I have a feeling the price for a 1 x 1.5 m glass will be out of my budget.
I have seen talk of :
- window film (which to me does not seem like it could work because of the tinting ?) Are there any other products, domestic or otherwise that have the same properties as a Beam splitter coating (being transparent and anti-reflective) ?
- teleprompter glass / half-silvered mirror - I'm not sure how this could work ?
The best projecter position to me seems to be the setup Eyeliner uses, so I'm considering this arrangement : Google Image Result for http://cdn.uproxx.com/wp-content/uploads/2012/04/tupac-hologram-diagram.jpg
As well as the traditional "L" shaped spatial configuration : http://tinyurl.com/bl48rtp
I have considered rear-projecting, but hot-spots seem unavoidable (am i wrong?) and all the 'transparent' rear projection screens I have seen (sometimes advertised as 'holo-screen') are not actually transparent, but a very light grey colour.
Any leads are welcome !
