This laser hyperspectral imaging system (Laser-HSI) can be used for sorting tasks and for continuous quality monitoring. The system uses a 532 nm Nd:YAG laser and a standard pushbroom HSI camera. Depending on the lens selected, it is possible to cover large areas (e.g., field of view (FOV) = 386 mm) or to achieve high spatial resolutions (e.g., 0.02 mm). The developed Laser-HSI was used for four exemplary experiments: (a) the measurement and classification of a mixture of sulphur and naphthalene; (b) the measurement of carotenoid distribution in a carrot slice; (c) the classification of black polymer particles; and, (d) the localization of impurities on a lead zirconate titanate (PZT) piezoelectric actuator. It could be shown that the measurement data obtained were in good agreement with reference measurements taken with a high-resolution Raman microscope. Furthermore, the suitability of the measurements for classification using machine learning algorithms was also demonstrated. The developed Laser-HSI could be used in the future for complex quality control or sorting tasks where conventional HSI systems fail.<\/jats:p>","DOI":"10.3390\/jimaging4100110","type":"journal-article","created":{"date-parts":[[2018,9,21]],"date-time":"2018-09-21T11:00:25Z","timestamp":1537527625000},"page":"110","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Hyperspectral Imaging Using Laser Excitation for Fast Raman and Fluorescence Hyperspectral Imaging for Sorting and Quality Control Applications"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9405-797X","authenticated-orcid":false,"given":"Florian","family":"Gruber","sequence":"first","affiliation":[{"name":"Department Chemical Surface and Reaction Technology, Fraunhofer Institute for Material and Beam Technology (IWS) Dresden, Winterbergstr. 28, 01277 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4473-9750","authenticated-orcid":false,"given":"Philipp","family":"Wollmann","sequence":"additional","affiliation":[{"name":"Chair for Electrochemistry, Technische Universitaet Dresden, Zellescher Weg 19, 01069 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wulf","family":"Gr\u00e4hlert","sequence":"additional","affiliation":[{"name":"Department Chemical Surface and Reaction Technology, Fraunhofer Institute for Material and Beam Technology (IWS) Dresden, Winterbergstr. 28, 01277 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Kaskel","sequence":"additional","affiliation":[{"name":"Department Chemical Surface and Reaction Technology, Fraunhofer Institute for Material and Beam Technology (IWS) Dresden, Winterbergstr. 28, 01277 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Borengasser, M., and Hungate, W.S.
