Here, we introduce a Fisher-information framework for optimizing linearly and circularly polarized excitation schemes under a fixed total illumination photon budget. For the multi-view reflector microscope, 3000 illumination photons, and 7.5 detected background photons per pixel, an optimized four-frame linear scheme improves median orientation measurement precision by 21.2% relative to the conventional six-frame equal-pumping scheme and achieves Cram\u00e9r\u2013Rao-bound-limited median precisions of\n                    <jats:italic>\u03c3<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>\u03b8<\/jats:italic>\n                      ,50\n                    <\/jats:sub>\n                    =2.59\n                    <jats:sup>\u2218<\/jats:sup>\n                    and\n                    <jats:italic>\u03c3<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>\u03d5<\/jats:italic>\n                      ,50\n                    <\/jats:sub>\n                    =3.22\n                    <jats:sup>\u2218<\/jats:sup>\n                    . Increasing to six optimized linear frames provides only modest additional improvement, demonstrating that four frames offer an effective balance between precision, uniformity across molecular orientations, and temporal resolution. With only two frames, circularly polarized excitation yields more uniform performance and 27% better median precision than two-frame linear excitation, whereas linear schemes perform better with four or more frames. Applying the framework to four engineered dipole-spread functions shows that excitation sequences should be tailored to the detection system. These results provide practical strategies for balancing orientation precision, photon budget, and acquisition speed in SMOLM.\n                  <\/jats:p>","DOI":"10.1364\/boe.607950","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T05:00:08Z","timestamp":1786942808000},"page":"4854","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimal excitation polarization schemes to boost the precision of single-molecule orientation imaging"],"prefix":"10.1364","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9814-5444","authenticated-orcid":true,"given":"Kaizhi A.","family":"Nie","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01yc7t268","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4548-3057","authenticated-orcid":true,"given":"Yuanxin","family":"Qiu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01yc7t268","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5614-3292","authenticated-orcid":true,"given":"Matthew D.","family":"Lew","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01yc7t268","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"boe-17-9-4854-R1","doi-asserted-by":"publisher","first-page":"1486","DOI":"10.1364\/OPTICA.502119","type":"journal-article","volume":"10","author":"Brasselet","year":"2023","journal-title":"Optica"},{"key":"boe-17-9-4854-R2","doi-asserted-by":"publisher","first-page":"e17","DOI":"10.1017\/S0033583524000167","type":"journal-article","volume":"57","author":"Zhang","year":"2024","journal-title":"Q.
