- ПубликацияОткрытый доступRADIOVISION IN THE TERAHERTZ RANGE: PROBLEMS AND PROSPECTS(НИЯУ МИФИ, 2023) Chistyakov, A. A.; Akmalov, A. E.; Kotkovskii, G. E.; Kozlovskii, K. I.; Maksimov, E. M.; Martynov, I. L.; Osipov, E. V.; Kuzishchin, Yu. A.; Plekhanov, A.

Various sources of terahertz radiation are considered: photoconductive antennas, IMPATT diodes, Schottky diodes, and others, as well as modern video cameras for this range and their main characteristics for recording and studying THz images in various spectral regions. The results of studies of the intensity distribution in THz radiation beams at diff erent wavelengths for photoconductive antennas using THz radiovision, as well as the possibilities of studying scattering processes during refl ection and transmission of THz radiation for various materials, are presented.

This work is devoted to the study of the detection of trace amounts of 1,3,5-Trinitro-1,3,5-triazinane (RDX) in the form of particles localized in millimeter and submillimeter sizes using THz imaging with spectral resolution. As a result of the work, images of trace amounts of RDX in reflected THz radiation were obtained. The contrast in these images made it possible to detect single particles of the powdery substance. The difference in contrast for RDX and polyethylene (PE) in the obtained terahertz images makes it possible to use THz imaging with spectral resolution not only for detection, but also for the identification of chemical compounds.
- ПубликацияТолько метаданныеSol–Gel Derived Photonic Crystals BaTiO3/SiO2(2021) Kholov, P. A.; Karnilava, Y. D.; Lashkovskaya, E. I.; Raichenok, T. F.; Gaponenko, N. V.; Labunov, V. A.; Martynov, I. L.; Osipov, E. V.; Chistyakov, A. A.; Kargin, N. I.; Гапоненко, Николай Васильевич; Лабунов, Владимир; Мартынов, Игорь Леонидович; Осипов, Евгений Валерьевич; Чистяков, Александр Александрович; Каргин, Николай Иванович© 2021, Pleiades Publishing, Ltd.Abstract: It is shown for the first time that multilayer periodic BaTiO3/SiO2 structures formed by the sol–gel method are tunable photonic crystals with dependence of the photonic band gap from the temperature of the sample. The shift of the minimum in the reflection spectrum in the photonic band gap is observed from 616 to 610 nm in the sample-temperature range from +184 to +24°C, respectively, and is reproduced for several samples synthesized at a temperature of 450°C.

A.; Kotkovskii, G. E.; Kuzishchin, Y. A.; Martynov, I. L.; Osipov, E. V.; Pashkevich, A. A.; Акмалов, Артём Эдуардович; Чистяков, Александр Александрович; Котковский, Геннадий Евгеньевич; Кузищин, Юрий Александрович; Мартынов, Игорь Леонидович; Осипов, Евгений Валерьевич; Пашкевич, Александра Андреевна© 2021 SPIECurrently, one of the most important application of flow cytometry is the real-time analysis of aerosols, in particular, to ensure biosafety. In most cases, such analysis is aimed at detecting fluorescent signals from aerosol particles corresponding to the light emission of tryptophan and nicotinamide adenine dinucleotide (NADH). Further development of the method is largely related to the improvement of the light detecting systems for recording and processing of fluorescence and scattered light signals. In this work, a comparative analysis of flow cytometers for bioaerosols detection based on photo-multiplier tubes (PMT) and avalanche photodiodes (APD) operating in analog and photon-counting modes was carried out. The limit of detection (LOD) of bioaerosols, response time and ability to detect particles with low scattering and fluorescence cross section were calculated and examined. The calculations were carried out for the well-known optical scheme of fluorescence detection based on discrete photodetectors and dichroic mirrors combined with an air flow chamber equipped with elliptical and spherical mirrors. An ultraviolet light emission diode (LED) was used as a model source of exciting radiation. To estimate the optical properties of aerosol particles, experimental results obtained for a model bovine serum albumin bioaerosol and published data on various other bioaerosols were used. The calculation of the total number of fluorescent photons, emitted by particles of various sizes while passing the flow chamber was carried out. The obtained data were compared with parameters of photodetectors operating in analog and photon-counting modes. The critical particle size was determined for the effective registration in a photon-counting mode. Considering the size distribution of aerosol particles, it was concluded that application of the photon-counting mode will reduce the LOD of bioaerosols by more than an order of magnitude.
