Original abstract
If the investigated object cannot be transported to the laboratory or even canot be reached by an optical-fibre LIBS system, an open-field remote LIBS setup could be used. Objects like paintings, pottery, sculptures and all metal, glass or stone artefacts and historical buildings can be studied. This work describes the development and some preliminary results obtained by an open-field remote LIBS system in the following setup: Solar LQ-916 NdYAG pulsed laser as the source for creating the luminous micro plasma, Galilean type focusing optics to expand and focus the laser beam, Newtonian telescope as the collecting optics and monochromator Lot Oriel 260i with ICCD Andor Istar 734 camera.
Czech abstract
Pro analyzované předměty které nemohou být dopraveny do laboratoře, popřípadě nemohou být analyzovány pomocí LIBS systémů s optickými vlákny, lze využít LIBS zařízení s dálkovou detekcí. Touto technikou mohou být studovány např. malby, keramika, sochy, kovové či skleněné artefakty či budovy. Tato práce představuje vývoj a některé predběžné výsledky získané dálkovým LIBS systémem s otevřenou dráhou paprsku a snímaného záření. Systém je složen z pulsního laseru Solar LQ-916 NdYAG jako zdroje buzení mikroplazmatu, fokusačního (Galileova) teleskopu, sběrné optiky na bázi Newtonova teleskopu a monochromátoru Lot Oriel 260i s ICCD detektorem Andor Istar 734.
