The sensor utilizes a magneto-optic fluid comprising barium hexaferrite nanoplatelets that become birefringent in the presence of an external magnetic field and a compact fiber-optic sensor system for tracking the liquid\u2019s optical axis direction. An efficient temperature compensation system is provided which allows the use of otherwise highly temperature-sensitive magneto-optic liquids. An unambiguous measurement range of 90\u00b0 and a resolution of better than 0.05\u00b0 are demonstrated experimentally.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Optics Letters<\/strong> Vol. 47,<a href=\"https:\/\/opg.optica.org\/ol\/issue.cfm?volume=47&amp;issue=18\">Issue 18<\/a>,pp. 4696-4699(2022) <a href=\"https:\/\/doi.org\/10.1364\/OL.470646\">https:\/\/doi.org\/10.1364\/OL.470646<\/a><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/au.jovo.cc\/leoss\/wp-content\/uploads\/sites\/2\/2023\/01\/Visualization_1.mp4\"><\/video><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This Letter describes a miniature Fabry\u2013Perot, contactless, magneto-optic sensor for angular position measurement.
