The conoscopic analysis of interference fringes is one of the most useful tools to investigate the mechanical properties of a crystal. These fringes are generated by a surface of constant phase difference called "Bertin surface" whose shape depends on the piezooptic properties of the material and on the applied stress. Here we investigate systematically for the first time these surfaces as algebraic surfaces. We also describe their dependence on the stress when these are "small" and give a detailed analysis for all crystallographic classes.

Abstract
The conoscopic analysis of interference fringes is one of the most useful tools to investigate the mechanical properties of a crystal. These fringes are generated by a surface of constant phase difference called "Bertin surface" whose shape depends on the piezooptic properties of the material and on the applied stress. Here we investigate systematically for the first time these surfaces as algebraic surfaces. We also describe their dependence on the stress when these are "small" and give a detailed analysis for all crystallographic classes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
