                                                          1.Rezime


               U  ovom  istraživanju  pokušao  sam  da  dokažem  prednosti  Digitalne  Holografske  Interferometrije  kao  vrlo
               sofisticiranu  analitičku  metodu  za  mehaničku  opzervaciju  jačina  i  deformacija  kod  različitih  materijala.Tokom
               istraživanja  testirao  sam  jačine  i  deformacije  kod  mechanickih  komponenata  kao  što  su  zubčanici,  takodje  sam
               testira i zubarske materijale.Mehaničke komponente su zubčanici različitih obima i struktura.Zubarski materijali su
               različiti  kompoziti,  plombe  i  cementi  koji  su  svetlosno  polimerizujući  materijali.Ovi  materijali  kada  se  izlože
               odredjenom  svetlosnom  spektrumu  oni  se  stvrdnjavaju.Cilj  mog  rada  je  bio  da  dokažem  mogućnosti  i  prednosti
               Digitalne Holografske Interferometrije.Takodje i da testiram različite komponente ovom  metodom kako bih se u
               budućnosti mogle unaprediti karakteristike svakog materijala koji bih bio izdržjiviji i dugotrajniji.

               In  this  investigation  I  attempt  to  prove  advantages  of  Digital  Holography  Interferometry  as  very  sophisticated
               analytical  method for  mechanical observation of strength  and strain forces  within different  materials. During  mi
               investigation I tested strength and strain forces exerted on mechanical components such as gear wheels and on dental
               materials.  Mechanical  components  are  gear  wheels  which  differ  in  perimeter  and  structure.  Dental  resins  are
               different composites, resins and cements which are light polymerization materials. Those materials when exposed to
               certain  light  spectrum  begin  to  cure.  The  aim  of  my  study  was  to  prove  possibilities  and  advantages  of  Digital
               Holography Interferometry. Also to test different components by this method to observe their weak points and in
               future  to  improve  their  characteristics.  This  method  can  cause  that  materials  in  future  be  more  permanent  and
               durable.
