Va. Babenko et al., Detection of internal flaws in highly refractive crystals with the help ofa holographic microscope, RUSS J NOND, 36(9), 2000, pp. 701-703
Feasibility of contactless investigations of internal structure of transpar
ent crystals with high refraction indices, in particular, diamonds, using t
he technique of scanning a real reconstructed image of an object has been s
tudied. investigations were performed using an in-house designed smalt holo
graphic interference microscope.
