The project includes the development of an innovative optical tomograph based on absorption spectrometry, a breakthrough solution in industrial tomography. Unlike traditional methods of light intensity analysis, our solution focuses on the analysis of the light spectrum passing through the test medium, enabling precise and rapid detection of chemical components and accurate determination of the state. The project focuses on the development of an advanced device consisting of innovative fiber multiplexers, enabling fast switching between measurement channels and an extensive technique of spectrum testing, for its spatial distribution using computational intelligence. The unique approach of the proposed optical tomograph allows for the analysis of near-infrared objects. The final result of the measurement using spectrometry is a map of the distribution of individual chemical components inside the tank, containing information on the percentage of these substances. By utilizing a 16-channel fiber optic configuration, the product offers high-precision real-time location of chemical compounds, taking into account their spatial distribution. Currently, there is no other solution on the market that guarantees such a detailed analysis and location of chemical components. The project assumes the development of a pioneering optical tomograph, which uses absorption spectrometry technology along with a system of strict localization of chemical substances. It significantly exceeds the existing solutions, introducing an excellent diagnostic tool to the market.
