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) <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><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-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"352\" data-id=\"1386\" src=\"\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/getimagev2.jpg\" alt=\"\" class=\"wp-image-1386\" srcset=\"https:\/\/au.jovo.cc\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/getimagev2.jpg 500w, https:\/\/au.jovo.cc\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/getimagev2-300x211.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This Letter describes a miniature Fabry\u2013Perot, contactless, magneto-optic sensor for angular position measurement.
