Model interferogram I - Holografska deformacijska analiza realnih objekata

A graphical-numerical method, using desk top microcomputer, for constructing model interferograms based on principles proposed by Janta & Mueller(1974) is presented. For deformation analysis purpose the model interferogram method relays with operators experience and ability to estimate possible set of object behaviours under given conditions. Numericaly calculated and graphicaly presented model interferogram is compared through error and trial precedure with holographicaly obtained fringe pattern. The best fit is subjkectively estimated. The method was presented through tipical example of expanding sphere. It¨s potential for realistic complex objects deformation evaluation is presented with the analysis of complex human illius bone deformation under quzifiziological load.
