abstract = "U istraživanju materijala u čvrstom stanju raznih gabarita, od relativno malih objekata do naslaga ispod građevina, ili uopšte, istorijski se, od potpuno nezavisnih metoda merenja iz oblasti mehaničkih ispitivanja, preko akustičkih (ultrazvuk), danas prešlo na nove metode koje uključuju optičke prilaze. Gotovo paralelna istraživanja u sprezi optike i akustike se i na molekularnom nivou (razblaženi i koncentrovani rastvori malih molekula i makromolekula, polimera, emulzije, micele) proučavaju putem procesa rasejanja laserskih snopova. Poslednji stadijum je vezan za metode merenja koherentnih snopova, koje vezuju i velika gustina snage i spektralna gustina i energije i snage.
Primena metoda talasne optike i razni stepeni kompleksnosti pojava, koje uključuju refleksiju, interferenciju i difrakciju (uz deskripciju polarizacije), već dugo podrazumeva specifične pristupe za profesionalna ispitivanja u mašinstvu i građevinarstvu. To znači da je s obzirom na širinu pojma kulturne baštine, sva ova iskustava je moguće iskoristi i za objekte kulturne baštine.
U radu se opisuju, vrši izbor i pokazuju neke mogućnosti metoda, gde se uz seizmiku pojavljuju laserske metode. Za posebna izvršena merenja akustičkih podataka o materijalu objekata kulturne baštine, vrši se procena njihovih mehaničkih osobina (elastičnih modula) i traži skup drugih konstanti koje će upotpuniti prirodu artefakta., In the research of materials in solid state of various gabarits, from relatively small facilities to the deposits below buildings, or in general, historically, from fully independent measurement in the field of mechanical tests, through the acoustic (ultrasound) to new methods involving optical approaches. Almost parallel research in the optics and acoustics are also at the molecular level (diluted and concentrated solutions of small molecules and macromolecules, polymers, emulsions, miceles) are studied through the process of dispersion of laser beams. The last stage is related to the methods of measuring coherent beams, which also bind large density and spectral density and energy and power.
Application of the wave optics method and various degrees of complexity, which include reflection, interference and diffraction (with descriptions of polarization), has long imply specific approaches for professional testing in mechanical engineering and construction. This means that in view of the latitude of the term cultural heritage, all this experience can be used for cultural heritage facilities.
The paper describes, performs and show some possibilities of methods, where laser methods appear with seismic. For special measurements of acoustic data on the material of cultural heritage, the assessment of their mechanical properties (elastic modules) and requires a set of other constants that will complete the nature of the artifact.",
