An LED light source is used to illuminate the sample, and two orthogonally tilted step-structure glass plates are inserted into the optical path. By merely displacing the glass plates under cm-level precision, a series of holograms with sub-pixel displacements can be obtained. Combined with our improved pixel super-resolution (PSR) algorithm, high-quality PSR phase imaging can be achieved. Tests on the high-resolution USAF1951 target demonstrate that the system can achieve a half-width resolution of 870\u2005nm by a camera with a pixel size of 1.67\u2005\u00b5m. Additionally, imaging experiments were conducted on phase-type sinusoidal gratings, yeasts, red blood cells, and lilium ovary sections, respectively. The results show that the system can achieve large field-of-view, high-resolution phase imaging under low-cost hardware conditions and holds promise for its applications in biology and medicine.<\/jats:p>","DOI":"10.1364\/ol.536909","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T12:00:09Z","timestamp":1726833609000},"page":"5838","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Lensless super-resolved quantitative phase imaging with cm-level lateral translations of two glass plates"],"prefix":"10.1364","volume":"49","author":[{"given":"Yu","family":"Peng","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vevwk45","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Key Laboratory of Optical Information Detecting and Display Technology in Zhejiang Province"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuncong","family":"Huang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vevwk45","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Key Laboratory of Optical Information Detecting and Display Technology in Zhejiang Province"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7977-3609","authenticated-orcid":true,"given":"Yong","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vevwk45","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Key Laboratory of Optical Information Detecting and Display Technology in Zhejiang Province"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingjiang","family":"Han","sequence":"additional","affiliation":[{"name":"Zhejiang Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weimin","family":"Jin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vevwk45","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Key Laboratory of Optical Information Detecting and Display Technology in Zhejiang Province"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lihong","family":"Ma","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vevwk45","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Key Laboratory of Optical Information Detecting and Display Technology in Zhejiang Province"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,10,7]]},"reference":[{"key":"ol-49-20-5838-R1","author":"Bhandari","year":"2022"},{"key":"ol-49-20-5838-R2","doi-asserted-by":"publisher","first-page":"4","DOI":"10.1016\/j.ymeth.2017.08.013","volume":"136","author":"Wu","year":"2018","journal-title":"Methods"},{"key":"ol-49-20-5838-R3","doi-asserted-by":"publisher","first-page":"106326","DOI":"10.1016\/j.optlaseng.2020.106326","volume":"137","author":"Fennell","year":"2021","journal-title":"Opt.
