However, due to their high cost and reduced transportability, access to them for screening and surgical planning is still limited in low-resource and remote settings. To increase patients\u2019 access to optical biometry we propose a novel low-cost frequency-domain optical delay line (FD-ODL) based on an inexpensive stepper motor spinning a tilted mirror, for integration into a time-domain (TD)-biometer, amenable to a compact footprint. In the proposed FD-ODL, the axial scan range and the A-scan rate are decoupled from one another, as the former only depends on the spinning mirror tilt angle, while the A-scan rate only depends on the motor shaft rotational speed. We characterized the scanning performance and specifications for two spinning mirror tilt angles, and compared them to those of the standard, more expensive FD-ODL implementation, employing a galvanometric scanner for group delay generation. A prototype of the low-cost FD-ODL with a 1.5 deg tilt angle, resulting in an axial scan range of 6.61 mm and an A-scan rate of 10\u2005Hz was experimentally implemented and integrated in a dual sample beam optical low-coherence reflectometry (OLCR) setup with a detour unit to replicate the measurement window around the anterior segment and the retina. The intraocular distances of a model eye were measured with the proposed low-cost biometer and found to be in good agreement with those acquired by a custom swept-source optical coherence tomography (SS-OCT) system and two commercial biometers, validating our novel design.<\/jats:p>","DOI":"10.1364\/boe.501889","type":"journal-article","created":{"date-parts":[[2023,10,27]],"date-time":"2023-10-27T16:00:07Z","timestamp":1698422407000},"page":"6521","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Long-range frequency-domain optical delay line based on a spinning tilted mirror for low-cost ocular biometry"],"prefix":"10.1364","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-8396-3891","authenticated-orcid":true,"given":"Mar\u00eda Pilar","family":"Urizar","sequence":"first","affiliation":[{"name":"2EyesVision S.L."},{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrique","family":"Gambra","sequence":"additional","affiliation":[{"name":"2EyesVision S.L."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2873-3412","authenticated-orcid":true,"given":"Alberto","family":"de Castro","sequence":"additional","affiliation":[{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1lvaro","family":"de la Pe\u00f1a","sequence":"additional","affiliation":[{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Pascual","sequence":"additional","affiliation":[{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Onur","family":"Cetinkaya","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry, Polish Academy of Sciences (IPC-PAS)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5511-1697","authenticated-orcid":true,"given":"Susana","family":"Marcos","sequence":"additional","affiliation":[{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"},{"name":"University of Rochester"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6855-0074","authenticated-orcid":true,"given":"Andrea","family":"Curatolo","sequence":"additional","affiliation":[{"name":"Instituto de \u00d3ptica \u2018Daza de Vald\u00e9s\u2019"},{"name":"Institute of Physical Chemistry, Polish Academy of Sciences (IPC-PAS)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,11,29]]},"reference":[{"key":"boe-14-12-6521-R1","doi-asserted-by":"publisher","first-page":"47","DOI":"10.1097\/ICU.0b013e32834cd63e","volume":"23","author":"Sahin","year":"2012","journal-title":"Current Opinion in Ophthalmology"},{"key":"boe-14-12-6521-R2","doi-asserted-by":"publisher","first-page":"94","DOI":"10.17925\/EOR.2016.10.02.94","volume":"10","author":"Turczynowska","year":"2016","journal-title":"European Ophthalmic Review"},{"key":"boe-14-12-6521-R3","doi-asserted-by":"publisher","first-page":"472","DOI":"10.1111\/j.1755-3768.2007.00879.x","volume":"85","author":"Olsen","year":"2007","journal-title":"Acta Ophthalmol.
