Optica Photonic Devices Industry Summit at ficonTEC

05 - 06 September, 2023

Achim, Germany

Viacheslav (Slava) Artyushenko

The latest fiber-optic techniques in spectral range from UV to mid-infrared will be reviewed for research and industrial applications. Fiber optic probes enable to run sampling-free remote process monitoring. Depending on the chemical process & media to be analyzed, fiber probes can be based on 4 different fiber types selected for the required spectral range and used for Transmission, Reflection, ATR-absorption, Raman & Fluorescence spectroscopies. Advanced fiber optic combi probes are capable to utilize two spectroscopic methods at the same time assembled in the same probe shaft - such as Mid-FTIR+Fluorescence, Raman+Near IR, Raman+Mid-FTIR and others. It improves selectivity and precision of the analysis for media content in process control.

Robust fiber probes are reliable in a variety of applications, including harsh environments, such as wide temperature range from -150°C to +250°C, high pressure up to 200 Bar or in vacuum, aggressive liquids or gases, electromagnetic fields, including microwave and hard radiation and vibrations.

In the case of complex samples, single spectroscopic technique may be not sufficient for reliable control and monitoring of the process. Such challenging analytical tasks may require an optical diagnostic where different spectroscopic methods are combined to achieve better accuracy. In this case, the capability of the combined methods to deliver complementary chemical information creates a synergy. Moreover, advanced fiber optic combi probes collect spectral information from the same spot. In addition, the process can be investigated in the laboratory using all kinds of spectroscopy techniques. Several examples of different fiber spectroscopy applications will be presented using different methods and their combinations. Based on the results, a customized sensor based on a few, but key informative spectral bands can be developed - with reduced size and cost.

About the Speaker

Dr. Viacheslav Artyushenko was born in 1954 and got his PhD in physics of solid state in 1981 – focused on his pioneering development of unique technology of polycrystalline fibers for Mid IR-range: 3-18µm. His multiple publications and patents were devoted to specialty fiber optic technologies and their applications in laser surgery and diagnostics, in process-spectroscopy and fiber optic sensing. In 1998, he has founded art photonics GmbH in Berlin – one of the worldwide leading manufacturers of various fibers, cables, bundles and spectroscopy probes used in very broad spectral range 0.3-16µm for many industrial, medical, scientific and other applications. Dr. V. Artyushenko is member of EPIC, CPACT, SPIE, OSA, SAS, SPECTARIS, Optec-BB, Photonics-BB, GDCh-DECHEMA & CLIRSPEC.
