However, conventional CP struggles\n\t\t\t\t\tto recover low-frequency phase components, as these cannot be\n\t\t\t\t\teffectively converted into detectable intensity variations through\n\t\t\t\t\tcoded image sensor translation, limiting reconstruction fidelity.\n\t\t\t\t\tHere, we report a novel lensless microscopy method that integrates\n\t\t\t\t\tmulti-angle illumination with coded ptychographic phase retrieval. In\n\t\t\t\t\tthis platform, the tube lens is laterally translated to generate\n\t\t\t\t\tangle-varied plane waves as phase diversity measurements, while a\n\t\t\t\t\tcoded image sensor beneath the object captures the resulting\n\t\t\t\t\tdiffraction patterns. The spatial modulation provided by the coded\n\t\t\t\t\tlayer imposes support constraints for quantitative phase recovery. To\n\t\t\t\t\taddress the issue of positioning accuracy, we directly recover the\n\t\t\t\t\tincident beam angles from the captured images. To overcome the\n\t\t\t\t\tchallenge of restoring the slow-varying phase contents with multiple\n\t\t\t\t\t2\u03c0 wraps, we conduct a calibration experiment to characterize\n\t\t\t\t\tthe transmission profile of the coded layer, providing deterministic\n\t\t\t\t\tconstraints for the phase retrieval process. We validate the proposed\n\t\t\t\t\tapproach using various samples. The approach achieves a 5.6\u2009mm\n\t\t\t\t\tby 7.4\u2009mm FOV with a half-pitch resolution of\n\t\t\t\t\t0.96\u2009\u03bcm. It offers a large FOV, high-resolution, and\n\t\t\t\t\tquantitative on-chip microscopy, making it adaptable for applications\n\t\t\t\t\tin point-of-care, global health, and telemedicine.<\/jats:p>","DOI":"10.1364\/ol.585444","type":"journal-article","created":{"date-parts":[[2026,4,2]],"date-time":"2026-04-02T15:00:12Z","timestamp":1775142012000},"page":"2588","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Lensless quantitative microscopy based on multi-angle illumination and coded ptychographic phase retrieval"],"prefix":"10.1364","volume":"51","author":[{"given":"Liming","family":"Yang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuge","family":"Xue","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2306-0391","authenticated-orcid":true,"given":"Pengming","family":"Song","sequence":"additional","affiliation":[{"name":"Guangzhou National Laboratory"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7931-9361","authenticated-orcid":true,"given":"Junwei","family":"Min","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1160-7903","authenticated-orcid":true,"given":"Meiling","family":"Zhou","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0373-5136","authenticated-orcid":true,"given":"Tong","family":"Peng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaopeng","family":"Shao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tengfei","family":"Wu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1723-6680","authenticated-orcid":true,"given":"Baoli","family":"Yao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0444j5556","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"ol-51-9-2588-R1","doi-asserted-by":"publisher","first-page":"495","DOI":"10.1107\/S0567739469001045","type":"journal-article","volume":"25","author":"Hoppe","year":"1969","journal-title":"Acta Crystallogr.
