For this purpose, they rely on sensors to assess and respond to the current room conditions. With an augmented demand for more dedicated control, the number of sensors used in parallel increases considerably. In this context, the present work focuses on optical sensors with three spectral channels used to capture color-related information of the illumination conditions such as their chromaticities and correlated color temperatures. One major drawback of these devices, in particular with regard to intelligent lighting control, is that even same-type color sensors show production related differences in their color registration. Standard methods for color correction are either impractical for large-scale production or they result in large colorimetric errors. Therefore, this article shows the feasibility of a novel sensor binning approach using the sensor responses to a single white light source for cluster assignment. A cluster specific color correction is shown to significantly reduce the registered color differences for a selection of test stimuli to values in the range of 0.003\u20130.008 \u0394u\u2032v\u2032, which enables the wide use of such sensors in practice and, at the same time, requires minimal additional effort in sensor commissioning.<\/jats:p>","DOI":"10.3390\/s21092950","type":"journal-article","created":{"date-parts":[[2021,4,23]],"date-time":"2021-04-23T01:25:56Z","timestamp":1619141156000},"page":"2950","source":"Crossref","is-referenced-by-count":5,"title":["Tackling Heterogeneous Color Registration: Binning Color Sensors"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5654-837X","authenticated-orcid":false,"given":"Paul","family":"Myland","sequence":"first","affiliation":[{"name":"Laboratory of Lighting Technology, Technical University of Darmstadt, Hochschulstr. 4a, 64289 Darmstadt, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8002-1220","authenticated-orcid":false,"given":"Sebastian","family":"Babilon","sequence":"additional","affiliation":[{"name":"Laboratory of Lighting Technology, Technical University of Darmstadt, Hochschulstr. 4a, 64289 Darmstadt, Germany"},{"name":"Department of Population Health Science and Policy, Light and Health Research Center, Icahn School of Medicine at Mount Sinai, One Gustave L.
