The aim of this investigation is to study the changes occurring on the surface of poplar wood exposed to artificial irradiation in a Solar Box. Colour changes were monitored with a reflectance spectrophotometer. Surface chemical modifications were evaluated by measuring the infrared spectra. Hyperspectral imaging was also applied to study the surface wood changes in the visible-near infrared and the short wave infrared wavelength ranges. The data obtained from the different techniques were compared to find the possible correlations in order to evaluate the applicability of the Hyperspectral imaging to investigate wood modifications in a non-invasive modality. The study of colour changes showed an important variation due to photo-irradiation which is the greatest change occurring within the first 24 hours. Infrared spectroscopy revealed that lignin degrades mainly in the first 48 hours. Concerning Hyperspectral imaging, the spectral features in the visible-near infrared range are mainly linked to the spectral shape, whereas in the short wave infrared cellulose and lignin affect shape and reflectance levels. The proposed approach showed that a correlation can be established between colour variation and wood degradation in the visible-near infrared range; furthermore in the short wave infrared region surface chemical changes can be assessed.

Hyperspectral reflectance imaging in the short-wave infrared range (SWIR, “extended NIR”, ca. 1000 to 2500 nm) has proven to provide enhanced characterization of paint materials. However, the interpretation of the results remains challenging due to the intrinsic complexity of the SWIR spectra, presenting both broad and narrow absorption features with possible overlaps. To cope with the high dimensionality and spectral complexity of such datasets acquired in the SWIR domain, one data treatment approach is tested, inspired by innovative development in the cultural heritage field: the use of a pigment spectral database (extracted from model and historical samples) combined with a deep neural network (DNN). This approach allows for multi-label pigment classification within each pixel of the data cube. Conventional Spectral Angle Mapping and DNN results obtained on both pigment reference samples and a Buddhist painting (thangka) are discussed.

Introduction. The Academy of State Fire Service of EMERCOM of Russia conducted tests of technical means of measuring the infrared range for detecting a fire source in the mobile firing range of the PTS "Lava". The results of tests for detecting both a fire source and a person in conditions of reduced visibility - in conditions of artificial smoke are presented. Goals and objectives. The purpose of the study is to determine the effectiveness of technical means of measuring the infrared range when training fire departments in conditions of reduced (zero) visibility. The objective of the study is to determine the source of ignition and the person in the artificial smoke by technical means of measuring the infrared range and analyzing the results obtained. Methods. When conducting a study on the detection of a fire source in the conditions of artificial smoke, scientific methods were used: analysis, synthesis and full-scale experiment. Results and their discussion. The results of tests at the PTS "Lava" firing range showed that when using a short-wave infrared camera, the detection range of both a fire source and a person in artificial smoke is five times greater than when using a visible range camera. The obtained results can be used in the educational process when preparing the personnel of fire departments for practicing professional skills. Conclusions. As a result of an experimental study on the detection of a fire source and a person in artificial smoke, the effectiveness of using a camera of the short-wave infrared range (SWIR-range) by fire departments when working in an environment unsuitable for breathing has been proved. Keywords: visibility, smoke, swir-range of the electromagnetic spectrum, fire source
