Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives
Main goal of the course is to inform students about principles and applications of optical methods, mainly lasers, in the protection of cultural heritage.
Learning outcomes
After the completion of this course the student will be able to independently select an appropriate optical method for documentation, conservation, cleaning and analysis of an object of cultural heritage in a laboratory and also on the spot of discovery in both contact and stand-off modes.
Syllabus
  • 1.Principle of laser, properties of laser irradiation, laser types used in the cultural heritage protection; interaction of laser beam with material.
  • 2.Plasma induced by laser, ultrasound. Diagnostics of laser plasma.
  • 3.Chemical reactions (pyrolysis, polymerization, cluster formation, … ) and degradation of materials by effect of laser.
  • 4.LIBS a LIF, interference (spectral and non-spectral), application of methods.
  • 5.Checking of cleaning process, deposition using LIBS, acoustic signal etc.
  • 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 artifacts 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 (microscopy) - pigment identification.
  • 14.Monitoring of artifact surface quality by interferometry.
  • 15.Exploitation of holographic techniques and scanning in survey, documentation and presentation of cultural heritage.
