Abstract

Registration of 3D ho1orarns broadens the possibility of using single-crystal tool for imagining and investigating inner inhomogeneities and dynamic stresses in top area of gem diamond, study of which by other techniques,e.g. polarization optics, is difficult or impossible. The difficulty is that the diamond with significant refractive index of 2.42 has comparatively small angle of total internal reflection of 24°50. As a result, with random illumination of the tops of octahedron diamond crystals, both smooth- faceted and with polycentric facets, illuminating light is successively reflected from different farets and absorbed in the crystal or comes out of it in a spot and direction that are difficult to calculate. Optimal schemes of illuminating crystals for recording 3D holograms of smooth faceted octahedron diamonds are given. Analysis of illumination of the crystal with polycentric facets shows that correction of light in the diamond is determined by directivity diagram the width of which depends in inhomogeneity size of the diamond. 3D holograms of diamonds with different reflectivity were produced. For the first time the possibility is shown for registration of holograms for studying stresses in diamond top using single-crystal tool.
