If you take 3 sonsecutive photographs through a red, a blue and a
green filter, the resulting pictures can be used to reproduce the original
colours of the subject. Taht's the principle of colour separation as it's
used in the offset procedure, for example.
Now I wonder what happened if you took 2 or 3 X-Ray photographs
through a same object, interposing successively 2 or 3 sheet of different
opaque materials. Could these radiographs be used to elaborate a coloured
picture, which would permit the optical distinction of different materials?
Anybody has proved that? Is there some literature about it?
And another question: If it does'nt work, why not?
Kind Regards
