The foundations for the development of a measuring device were laid with systematic fluorescence measurements on a wide range of characteristics of spruce trunk wood with and without red rot. In addition, a laboratory setup for imaging, spectrally resolved wood fluorescence was set up and tested. The device developed as part of the project makes it possible to use optoelectronic sensors to detect red rot on the cross-section of the trunk wood, to determine the location of the rot and to objectively classify it into different rot grades (healthy, axe- and nail-proof, soft rot). An objective quality measurement can thus be ensured and used for better economic utilization of the wood.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div style=\"height:70px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"600\" src=\"http:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_EEM-1024x600.jpg\" alt=\"\" class=\"wp-image-3774\" srcset=\"https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_EEM-1024x600.jpg 1024w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_EEM-300x176.jpg 300w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_EEM-768x450.jpg 768w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_EEM.jpg 1195w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Excitation-emission matrices of healthy sapwood (left), heartwood with beginning wood degradation (mi) and red-rotten heartwood (right), spruce, sawn<\/figcaption><\/figure>\n\n\n\n<div style=\"height:70px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"488\" src=\"http:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_Fluoreszenzspektren-1024x488.jpg\" alt=\"\" class=\"wp-image-3775\" srcset=\"https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_Fluoreszenzspektren-1024x488.jpg 1024w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_Fluoreszenzspektren-300x143.jpg 300w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_Fluoreszenzspektren-768x366.jpg 768w, https:\/\/www.gmbu.de\/wp-content\/uploads\/2021\/04\/FS_Jena_Projekt_Lignoscan_Fluoreszenzspektren.jpg 1203w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">fluorescence spectroscopy of artificially infected wood samples<\/figcaption><\/figure>\n\n\n\n<p> BMELV, FKZ: 22009713<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the research project \u201cQuality measurement of coniferous logs \u2013 Lignoscan\u201d, a prototype for the detection and assessment of red rot was developed and successfully tested in the sawmill together with experts from Th\u00fcringenForst and an SME based in Thuringia.
