DIGITAL HOLOGRAPHIC INTERFEROMETRY AS A PRECISION INSTRUMENT IN DENTISTRY
The paper the possibility of using digital holographic interferometry to obtain complete information about the nature of the distribution of loads and strains in the study of dental tissue. is shown. The optical scheme of the installation for measuring micro-deformations of the dental object under study in the loaded state is presented. The dynamics of deformation of the surface of the sample under increasing load is considered, and the pressure at which the destruction of the tooth occurred (P = 34 kgf) is determined. Photos that allow to make a qualitative analysis of the deformed single-rooted tooth are presented. The experiment proved its importance, since the application of the method of digital holographic interferometry with registration of holograms according to the Denisyuk scheme allows to make a qualitative assessment of displacements and deformations of the dental object.
