SUMMARY:CICS-Ringvorlesung (Hybrid): The contribution of multiphoton micros
 copy to our knowledge of parchments
DESCRIPTION:Multiphoton microscopy\, also called non-linear optical (NLO) m
 icroscopy\, is an optical imaging technique widely developed in the biomed
 ical field\, but relatively new and promising for the non-invasive analysi
 s of heritage materials. This technique is particularly efficient to inves
 tigate skin-based materials at the microscopic scale\, especially parchmen
 ts\, since it can visualise the collagen fibre organisation within the mat
 erial from the collection of the second harmonic generation (SHG) signal. 
 The simultaneous collection of fluorescence signals by the same NLO micros
 cope can also reveal the presence of interacting fluorescent materials suc
 h as fat\, elastin and keratin\, remaining from the skin preparation\, or 
 gelatin\, resulting from collagen degradation. When applied to historical 
 parchments and manuscripts\, NLO microscopy sometimes reveals very differe
 nt morphology of collagen fibres and signals collected\, likely associated
  to various factors in the life of the object. Based on experiments set up
  on modern parchments and measurements made on historical objects\, we wil
 l demonstrate how the technique can contribute to our knowledge on the man
 ufacturing\, the degradation and the impact of some restoration treatment 
 of parchments.
