Existing imaging techniques\u2014including digital holography and conventional light field imaging\u2014face a fundamental limitation in recovering the complete surface geometry of opaque and semi-transparent particles due to optical occlusion and limited perspective sampling. We overcome this challenge with a face-to-face dual light field camera (F2F-DLFC) system, which simultaneously captures both sides of a target under incoherent dark-field illumination. This dual-side snapshot strategy enables full 3D reconstruction of opaque particles, with experimental results showing volume errors below 6% for targets such as live fish and irregular pellets. While semi-transparent objects still present reconstruction challenges, this work establishes a foundational methodology for\n                    <jats:italic toggle=\"yes\">in-situ<\/jats:italic>\n                    volumetric instrument development, providing a viable approach for accurate volumetry of a wide range of underwater particles.\n                  <\/jats:p>","DOI":"10.1364\/ol.582735","type":"journal-article","created":{"date-parts":[[2025,12,11]],"date-time":"2025-12-11T16:00:09Z","timestamp":1765468809000},"page":"317","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Dual-side snapshot light field imaging for accurate 3D volumetry of opaque and drifting underwater particles"],"prefix":"10.1364","volume":"51","author":[{"given":"Fengming","family":"Huang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gh4er46","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Jinan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5553-4833","authenticated-orcid":true,"given":"Yifan","family":"Song","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gh4er46","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8241-0200","authenticated-orcid":true,"given":"Zibang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Jinan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0298-7406","authenticated-orcid":true,"given":"Zhisheng","family":"Zhou","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gh4er46","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangpei","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gh4er46","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7522-272X","authenticated-orcid":true,"given":"Jianping","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04gh4er46","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,1,6]]},"reference":[{"key":"ol-51-2-317-R1","doi-asserted-by":"publisher","first-page":"1227","DOI":"10.1016\/S0967-0637(99)00105-3","type":"journal-article","volume":"47","author":"Dilling","year":"2000","journal-title":"Deep-Sea Res.
