A longstanding challenge is that object or platform motion during acquisition is traditionally regarded as a source of blurring and degradation. Here, we present a paradigm in which object motion is reinterpreted as a beneficial source of sub-pixel sampling diversity rather than a detriment. By accurately tracking translational motion\u2014accomplished via geometric moment illumination patterns fused with Hadamard patterns\u2014we encode the known motion into the SPI forward model as structured perturbations. This approach converts motion from a blurring nuisance into a valuable imaging resource, effectively increasing the sampling density beyond the native grid. Incorporating the motion information directly into the inverse problem, we demonstrate that an enhanced-resolved reconstruction of the scene becomes achievable. The resulting linear measurement system, solved via total variation minimization, yields finer image details than SPI reconstructions acquired with a stationary target. Our work suggests that motion in SPI, far from being merely something to mitigate, can be harnessed to fundamentally improve SPI resolution and fidelity in dynamic scenes.<\/jats:p>","DOI":"10.1364\/oe.587584","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T05:00:08Z","timestamp":1770008408000},"page":"5558","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Motion-enhanced resolution in dynamic single-pixel imaging"],"prefix":"10.1364","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2303-1435","authenticated-orcid":true,"given":"Zijun","family":"Guo","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/034t30j35","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Science and Technology of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8728-5683","authenticated-orcid":true,"given":"Dongfeng","family":"Shi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/034t30j35","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Science and Technology of China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingjian","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/034t30j35","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Science and Technology of China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,2,5]]},"reference":[{"key":"oe-34-3-5558-R1","doi-asserted-by":"publisher","first-page":"83","DOI":"10.1109\/MSP.2007.914730","type":"journal-article","volume":"25","author":"Duarte","year":"2008","journal-title":"IEEE Signal Process.
