- ПубликацияТолько метаданныеUse of Direct Optical Heterodyning for Measuring Hardness by the Leeb Method(2019) Kazieva, T. V.; Gubskii, K. L.; Kuznetsov, A. P.; Glukhov, R. D.; Казиева, Татьяна Вадимовна; Губский, Константин Леонидович; Кузнецов, Андрей Петрович© 2019, Pleiades Publishing, Ltd.Abstract: In this paper, we describe a portable system for measuring the indenter velocity in hardness meters implemented according to the Leeb method. The developed system is a fiber interferometer, in which a radiation source is a semiconductor laser with a wavelength of 1550 nm. The presented experimental results confirm the ability of the system to measure indenter velocities with an uncertainty of 0.001 m/s, which satisfies the requirements of the standards for this method of measuring hardness.
- ПубликацияТолько метаданные3D push–pull heterodyne interferometer for SPM metrology(2019) Kazieva, T. V.; Gubskiy, K. L.; Kuznetsov, A. P.; Reshetov, V. N.; Казиева, Татьяна Вадимовна; Губский, Константин Леонидович; Кузнецов, Андрей Петрович; Решетов, Владимир Николаевич© 2019 Optical Society of America.A three-coordinate heterodyne laser interferometer has been developed to measure the displacement of the probe microscope scanner with a subnanometer resolution that provides traceability of measurements to the standard of meter through the wavelength of a stabilized He–Ne laser. Main sources of errors are investigated, and their influence is minimized so that the resulting measurement uncertainty of the system does not exceed 0.2 nm, and the resolution is 0.01 nm. The investigation of metrological characteristics of the three-coordinate interferometer was carried out with a scanning probe microscopy (SPM) NanoScan-3D using TGZ-type calibration gratings. The values measured with SPM fell within the 95% confidence interval given by Physikalisch-Technische Bundesanstalt (PTB) (Germany). SPM equipped with a laser interferometer was used to measure the characteristics of dynamic etalons of geometric dimensions.
- ПубликацияОткрытый доступMultichannel laser radiation collection and transport system for particle velocity measurements in shock wave experiments(2019) Tishenko, I. Y.; Gubskiy, K. L.; Pirog, V. A.; Kazieva, T. V.; Lukyanov, K. S.; Morozov, A. A.; Kuznetsov, A. P.; Тищенко, Илья Юрьевич; Губский, Константин Леонидович; Пирог, Владимир Андреевич; Казиева, Татьяна Вадимовна; Лукьянов, Константин Сергеевич; Кузнецов, Андрей Петрович© Published under licence by IOP Publishing Ltd.VISAR type measuring laser systems are used for the determination of surface velocities in high-speed processes. Their operational characteristics mostly depends on the efficiency of collection of scattered radiation. In this paper we present results of the comparative analysis of several radiation collection schemes along with experimentally obtained data on the scheme parameters effect on collection efficiency and recording length.
- ПубликацияОткрытый доступCombination of the velocity interferometer system for any reflector and the photon Doppler velocimetry methods to study transparent and absorbing condensed matter(2020) Ananev, S. Yu.; Grishin, L. I.; Kazieva, T. V.; Gubskiy, K. L.; Kuznetsov, A. P.; Tishchenko, I. Yu.; Glukhov, R. D.; Pirog, V. A.; Казиева, Татьяна Вадимовна; Губский, Константин Леонидович; Кузнецов, Андрей Петрович; Тищенко, Илья Юрьевич; Пирог, Владимир Андреевич© Published under licence by IOP Publishing Ltd.The paper proposes a method for combining photon Doppler velocimetry and a system of speed interferometers for any reflective systems, which allows one to study the behavior of transparent media under the action of powerful shock waves without the use of additional reflective surfaces. The paper presents the results of an experiment on the propagation of a shock wave in water. In this experiment, water was an absorber; however, the proposed method would also work provided that the test material is transparent and provides reflection.
- ПубликацияОткрытый доступHybrid interferometer system for velocity measurements(2020) Pirog, V. A.; Gubskiy, K. L.; Tishenko, I. Yu.; Kazieva, T. V.; Пирог, Владимир Андреевич; Губский, Константин Леонидович; Тищенко, Илья Юрьевич; Казиева, Татьяна Вадимовна© Published under licence by IOP Publishing Ltd.The first result of the developed hybrid system for measuring the mass velocity of a matter is presented in the article. It combines two methods, VISAR and PDV, to compensate for their shortcomings. The scheme of the measuring system and the results of the laboratory experiment are shown.
- ПубликацияОткрытый доступMetrological method for determining the surface area function of the nanohardness testers tips(2020) Kazieva, T. V.; Gubskiy, K. L.; Reshetov, V. N.; Kuznetsov, A. P.; Казиева, Татьяна Вадимовна; Губский, Константин Леонидович; Решетов, Владимир Николаевич; Кузнецов, Андрей Петрович© Published under licence by IOP Publishing Ltd.The paper describes a method for measuring the surface area function of the tips of the probes of nanohardness testers using a laser interferometer. The features of the developed system provide traceability of measurements to the standard of length through the wavelength of a stabilized source of laser radiation. In addition, it is possible to measure the parameters of the probe tip without removing it from the nanohardness tester, which allows the device not to be taken out of working condition and provides unambiguous measurements.
