In this first experimental setup the hyperspectral imaging (HI) system is made by a commercial photographic objective, the F-P interferometer and a 12-bit CCD camera. Between the objective and the F-P is placed an optical band pass filter (370-720 nm) needed to select the wanted portion of the spectrum. A blue laser @ 410 nm is used as reference for data analysis.

Two type of sample have been used:

• the first one is a Gretag Macbeth ColorCheker® illuminated by a xenon discharge lamp focused on a grounded glass acting as a diffuser,

• the second one is a coloured LED pattern realized in our laboratories.
