I think hyperspectral photography is very interesting. I want to do it bymyself and I need a tunable liquid crystal filter. Is there anyone who knows the technology. Which lc is tunable and transparent when colored ? What kind of a lc housing required ? Do electrodes needed to be transparent or electrodes at the sides usable ? What would be the thickness of the lc ? etc etc..
