Historical documents analyzed by the LIBS, LIF, colorimetryLIBS analysis used to control the laser cleaning process at 532 nm (on line and in situ) - removal of the blue pencil hand pagination

The cleaning is monitored by recording the spectra corresponding to consecutive

laser pulses Intensities of spectral lines due to surface

contaminants decrease exponentiallyLacona IV ‘2001, J.Cult.Herit.

The green pigment of the thorn crown; the elemental composition observed in the

visible spectral range by means of the LIBS technique agrees with the pigment

compounds found in the Raman spectra.
