To acquire the required sub-aperture spectral information, MFP typically employs convergent spherical-wave illumination to form the object spectrum at the camera aperture plane. However, the inherent property of a convergent wave causes the imaging field of view (FOV) to shrink as the imaging distance increases, which greatly limits its applicability in long-distance scenarios. Here, we propose a plane-wave-illuminated macroscopic Fourier ptychography (PI-MFP) method to achieve FOV-constant HR imaging for diffuse reflective objects at different imaging distances. By incorporating the phase term of plane-wave illumination and the imaging-distance-related quadratic phase factor into the phase of the diffuse reflective object, we establish a dummy-object forward imaging model for plane-wave-illuminated MFP to enable HR amplitude reconstruction without forming the object spectrum at the aperture plane. The effectiveness of the dummy-object model was quantitatively verified at different imaging distances and object-field extents. Imaging results on resolution targets from both simulations and experiments demonstrate a 2.8-fold resolution enhancement, approaching the theoretical threefold value. Furthermore, experiments on a Quick Response code demonstrate that PI-MFP maintains a constant FOV across an approximately threefold range of imaging distances, while experiments on a 1-yuan banknote confirm its HR imaging capability for everyday objects. These results establish PI-MFP as a practical method for long-distance HR imaging with potential applications in remote sensing and security surveillance.<\/jats:p>","DOI":"10.1364\/oe.611164","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T08:00:09Z","timestamp":1789113609000},"page":"37534","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Plane-wave-illuminated macroscopic Fourier ptychography with a constant field of view"],"prefix":"10.1364","volume":"34","author":[{"given":"Miaomiao","family":"Tang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3579-8473","authenticated-orcid":true,"given":"Yunpeng","family":"Feng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Shenzhen Research Institute of Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haobo","family":"Cheng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Shenzhen Research Institute of Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Le","family":"Yu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Shenzhen Research Institute of Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Zhao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Space Mechanics & Electricity"},{"name":"Beijing Key Laboratory of Advanced Optical Remote Sensing Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"oe-34-20-37534-R1","author":"Goodman","year":"2005"},{"key":"oe-34-20-37534-R2","doi-asserted-by":"publisher","first-page":"251","DOI":"10.1109\/TCI.2016.2557067","type":"journal-article","volume":"2","author":"Holloway","year":"2016","journal-title":"IEEE Trans.
