We present an open-source optical design that can be replicated with readily available commercial-off-the-shelf components, and an open-source software platform openhsi that simplifies the process of capturing calibrated hyperspectral datacubes. Some of the features that the software stack provides include: an ISO 19115-2 metadata editor, wavelength calibration, a fast smile correction method, radiance conversion, atmospheric correction using 6SV (an open-source radiative transfer code), and empirical line calibration. A pipeline was developed to customise the desired processing and make openhsi practical for real-time use. We used the OpenHSI optical design and software stack successfully in the field and verified the performance using calibration tarpaulins. By providing all the tools needed to collect documented hyperspectral datasets, our work empowers practitioners who may not have the financial or technical capability to operate commercial hyperspectral imagers, and opens the door for applications in new problem domains.<\/jats:p>","DOI":"10.3390\/rs14092244","type":"journal-article","created":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T23:27:25Z","timestamp":1652052445000},"page":"2244","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["OpenHSI: A Complete Open-Source Hyperspectral Imaging Solution for Everyone"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1585-0123","authenticated-orcid":false,"given":"Yiwei","family":"Mao","sequence":"first","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3797-2028","authenticated-orcid":false,"given":"Christopher H.","family":"Betters","sequence":"additional","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"},{"name":"Sydney Astrophotonic Instrumentation Laboratories, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6675-3118","authenticated-orcid":false,"given":"Bradley","family":"Evans","sequence":"additional","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"},{"name":"Defence Science and Technology Group, Eveleigh, NSW 2015, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9809-7098","authenticated-orcid":false,"given":"Christopher P.","family":"Artlett","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Eveleigh, NSW 2015, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5606-3874","authenticated-orcid":false,"given":"Sergio G.","family":"Leon-Saval","sequence":"additional","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"},{"name":"Sydney Astrophotonic Instrumentation Laboratories, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0622-8255","authenticated-orcid":false,"given":"Samuel","family":"Garske","sequence":"additional","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6978-9765","authenticated-orcid":false,"given":"Iver H.","family":"Cairns","sequence":"additional","affiliation":[{"name":"ARC Training Centre for CubeSats, UAVs & Their Applications, School of Physics, The University of Sydney, Sydney, NSW 2006, Australia"}]},{"given":"Terry","family":"Cocks","sequence":"additional","affiliation":[{"name":"HyVista Corporation Pty Ltd., Sydney, NSW 2152, Australia"}]},{"given":"Robert","family":"Winter","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Eveleigh, NSW 2015, Australia"}]},{"given":"Timothy","family":"Dell","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Eveleigh, NSW 2015, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jorden, P.R.
