Course objectives
Main goal of the course is to inform students students with applications of optical methods and lasers in the protection of cultural heritage.
Syllabus
  • 1.Principle of laser, prperties of lasr irradiation, laser types used in the cultural heritage protection; interaction of laser beam with material.
  • 2.Plasma induced by laser, supersound. Diagnostics of laser plasma.
  • 3.Chemical reactions (pyrolysis, polymerization, cluster formation, … ) and degradation of materials by effect of laser.
  • 4.LIBS a LIF, interference (spectrak and non-spectral), application of methods.
  • 5.Checking of cleaning process, deposition using LIBS, acoustic signal etc.v 6.Laser desorption of organic molecules (MALDI), laser ablation (with ICP), laser micropyrolysis (with GC-MS).
  • 7.Ablation in liquids, laser plasma in liquids, cavitation caused by laser.
  • 8.LIBS of solids in liquid media (analysis of artefacts under water) and analysis of suspensions and solutions. 9.Removing of corrosion products and undesirable surface preparations.
  • 10.Laser deposition of anticorrosive and protecting layers.Formation of coatings.
  • 11.Chemical synthesis by using laser.
  • 12.Advanced applications: measuring in longer distances by LIBS a LIF (diagnostics of building structures), LIDAR and its application in archaeological prospection.
  • 13.Connection of LIBS with Raman spectroscopy(mikroscopy)- pigment identification.
  • 14.Monitoring of artefact surface quality by interferometry.
  • 15.Exploitation of holographic techniques in survey, documentation and presentation of cultural heritage.
