Description

Gabriel Lippmann won the 1908 Nobel Prize in Physics for color photography.
It is actually the first example of multispectral imaging. We provide a complete analysis of the process and show, both theoretically and experimentally, what spectrum is reflected from a Lippmann plate.
An algorithmic recovery of the original spectrum is proposed, as well as a digital version of Lippmann photography.
We discuss the application to high-density permanent three-dimensional storage and finish with an example of science communication for the general public.
