This paper describes a system that uses the principle of heterodyne interferometry based on a two-frequency laser to interpret holograms obtained from a diffusely reflective surface. An estimate is given of the measurement error introduced by the optical elements of the system into the phase of the output signal.
The Raman spectra of amber (succinite) of different transparency levels of the Palmniken Deposit of Kaliningrad of Russia were obtained using the Fourier Transform–Raman spectroscopy method, which allows obtaining real and elemental compositions. It was found that succinite (amber) is an organic unsaturated carbon - chain homopolymer with different valence oscillations of aliphatic CH2 and CH3 groups, containing heteroatoms C=C and CH in the main chain with valence in RNS=CH2 and deformation in trans RHC=CHR' oscillations with chemical side chains of up to 8 subgroups. Three main connections were experimentally identified on the obtained Raman spectra, which can be used as characteristic features for identification and diagnostics of succinite of the Palmniken Deposit. Practical significance. The proposed method may be of interest for chemistry, materials science and research related to identification processes. The performed research can be used in the synthesis of high-molecular compounds, in issues related to the development and distribution of various applications of organic materials.
The solution of the problem of identification of amber (succinite) on the example of natural polymer material of organic origin on the basis of its infrared absorption spectra is proposed. Taking into account the growing demand for the use of such composite materials on an industrial scale and the insufficiency of existing methods for determining their composition, the proposed method can become a new solution to the problem of identification. The basis of the proposed method for the study of succinite using infrared spectroscopy is translucent spectroscopy, with the measurement of mirror and diffuse reflection. The samples amber of the Palmniken Deposit obtained in the city of Kaliningrad of the Russian Federation were used as the objects studied. The data of infrared spectra of succinite obtained by the proposed method of infrared spectroscopy are obtained and presented in comparison. Five main links on the obtained infrared spectra have been experimentally determined, which can be used as characteristic features for identification and diagnostics of succinite by the material composition. The proposed method may be of interest in the theory of knowledge of material science, research related to the processes of identification, processing of production of amber.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
