Earlier single-shot SPIFI configurations integrated a train of laser pulses, operated in an image plane conjugate to the object plane, and required a 2D detector.

The resultant improvement in spatial frequency support, characteristic of single-shot SPIFI, is shown to be conserved in this new architecture, to our knowledge. This advancement allows increased resolution of physical events gated by a femtosecond pulse.\n                  <\/jats:p>","DOI":"10.1364\/ao.573423","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T14:00:08Z","timestamp":1763474408000},"page":"10632","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fourier-plane spatial frequency modulation imaging: enhanced resolution imaging with a single, ultrashort pulse"],"prefix":"10.1364","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7641-4037","authenticated-orcid":true,"given":"Olivier","family":"Bernard","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05cb4rb43","id-type":"ROR","asserted-by":"publisher"}]},{"name":"\u00c9cole polytechnique f\u00e9d\u00e9rale de Lausanne"},{"name":"University of Wisconsin-Madison"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6455-1102","authenticated-orcid":true,"given":"Seth","family":"Cottrell","sequence":"additional","affiliation":[{"name":"Colorado School of Mines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0530-0435","authenticated-orcid":true,"given":"Randy","family":"Bartels","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05cb4rb43","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Wisconsin-Madison"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8409-4678","authenticated-orcid":true,"given":"Yves","family":"Bellouard","sequence":"additional","affiliation":[{"name":"\u00c9cole polytechnique f\u00e9d\u00e9rale de Lausanne"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeff","family":"Squier","sequence":"additional","affiliation":[{"name":"Colorado School of Mines"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2025,12,5]]},"reference":[{"key":"ao-64-35-10632-R1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1109\/ISCAS45731.2020.9180436","type":"journal-article","article-title":"A 1280 \u00d7 960 dynamic vision sensor with a 4.95-um pixel pitch and motion artifact minimization","volume-title":"IEEE International Symposium on Circuits and Systems (ISCAS)","author":"Suh","year":"2020"},{"key":"ao-64-35-10632-R2","doi-asserted-by":"publisher","first-page":"4243","DOI":"10.1021\/bi00717a027","type":"journal-article","volume":"13","author":"Oseroff","year":"1974","journal-title":"Biochemistry"},{"key":"ao-64-35-10632-R3","doi-asserted-by":"publisher","first-page":"115568","DOI":"10.1016\/j.measurement.2024.115568","type":"journal-article","volume":"240","author":"Wei","year":"2025","journal-title":"Measurement"},{"key":"ao-64-35-10632-R4","doi-asserted-by":"publisher","first-page":"S22702","DOI":"10.1117\/1.JBO.29.S2.S22702","type":"journal-article","volume":"29","author":"Pham","year":"2024","journal-title":"J.
