- 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.
- ПубликацияТолько метаданныеA Three-Phase PDV Signal-Processing Method that Eliminates the Influence of Acceleration on Determining Velocity(2022) Kazieva, T. V.; Tishchenko, I. Y.; Reshetov, V. N.; Gubskiy, K. L.; Pirog, V. A.; Казиева, Татьяна Вадимовна; Тищенко, Илья Юрьевич; Решетов, Владимир Николаевич; Губский, Константин Леонидович; Пирог, Владимир Андреевич© 2022, Pleiades Publishing, Ltd.Abstract: The interference method for determining the velocity of objects using direct optical heterodyning (photonic Doppler velocimetry) has become widespread due to the ease of setting up the fiber-optic system, the unambiguous results that it produces, and the wide possibilities for varying the measurement accuracy and temporal resolution. The accuracy of velocity measurements can be fractions of a percent, but there are a number of factors that interfere with this. For example, a change in the velocity of an object, that is, its movement with acceleration, leads to a broadening of the signal spectrum with an increase in the working time window and, as a result, to a decrease, rather than an increase, in the accuracy of measuring the velocity. In this letter, a method is proposed that allows one to compensate for the effect of acceleration on the accuracy of velocity measurement. The proposed model for processing the registered signals makes it possible to determine both the acceleration and the velocity of the object. The applied algorithm made it possible to avoid the expansion of the spectrum with an increase in the time window and to improve the accuracy of measuring the velocity of a freely falling body by an order of magnitude.
- 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.
