The evolution of optical instrumentation, in particular large-scale ring laser installations, such as G-ring and ROMY (ROtational Motion in seismologY), and their geoscientific application have contributed significantly to the emergence of this scientific field. The currently most advanced, large-scale ring laser array is ROMY, which is unprecedented in scale and design. As a heterolithic structure, ROMY\u2019s ring laser components are subject to optical frequency drifts. Such Sagnac interferometers require new considerations and approaches concerning data acquisition, processing and quality assessment, compared to conventional, mechanical instrumentation. We present an automated approach to assess the data quality and the performance of a ring laser, based on characteristics of the interferometric Sagnac signal. The developed scheme is applied to ROMY data to detect compromised operation states and assign quality flags. When ROMY\u2019s database becomes publicly accessible, this assessment will be employed to provide a quality control feature for data requests.<\/jats:p>","DOI":"10.3390\/s21103425","type":"journal-article","created":{"date-parts":[[2021,5,17]],"date-time":"2021-05-17T02:31:34Z","timestamp":1621218694000},"page":"3425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Automated Quality Assessment of Interferometric Ring Laser Data"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2422-7907","authenticated-orcid":false,"given":"Andreas","family":"Brotzer","sequence":"first","affiliation":[{"name":"Department of Earth and Environmental Sciences, Ludwig Maximilian University Munich, Theresienstr. 41, D-80333 Munich, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9509-4905","authenticated-orcid":false,"given":"Felix","family":"Bernauer","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, Ludwig Maximilian University Munich, Theresienstr. 41, D-80333 Munich, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3775-5058","authenticated-orcid":false,"given":"Karl Ulrich","family":"Schreiber","sequence":"additional","affiliation":[{"name":"Geodetic Observatory Wettzell, Research Unit Satellite Geodesy, Technical University of Munich, 93444 Bad Koetzting, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4088-1792","authenticated-orcid":false,"given":"Joachim","family":"Wassermann","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, Ludwig Maximilian University Munich, Theresienstr. 41, D-80333 Munich, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7242-6399","authenticated-orcid":false,"given":"Heiner","family":"Igel","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, Ludwig Maximilian University Munich, Theresienstr. 41, D-80333 Munich, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Igel, H., Bernauer, M., Wassermann, J., Schreiber, K., and Meyers, R.
