Through numerical simulations and optical experiments, we analyze the normalized cross-correlation of point spread functions and the quality of the reconstructed outputs for multiple object states. Simulated and experimental reconstructions show strong agreement, achieving high-fidelity reconstructions under matching conditions in experiments. These results demonstrate that spiral-phase-modulated I-COACH systems can encode and discriminate multidimensional optical states, establishing a foundation for incoherent holographic imaging across spatial, spectral, and OAM domains with potential applications in optical communication, beam diagnostics, and precision metrology. interferenceless coded aperture correlation holography vortex speckles diffraction 3D imaging holography Full Text Additional Declarations No competing interests reported.

Through numerical simulations and optical experiments, we analyze the normalized cross-correlation of point spread functions and the quality of the reconstructed outputs for multiple object states. Simulated and experimental reconstructions show strong agreement, achieving high-fidelity reconstructions under matching conditions in experiments. These results demonstrate that spiral-phase-modulated I-COACH systems can encode and discriminate multidimensional optical states, establishing a foundation for incoherent holographic imaging across spatial, spectral, and OAM domains with potential applications in optical communication, beam diagnostics, and precision metrology.\u003c/p\u003e","manuscriptTitle":"5D Information Encoding Using Spiral Phase Masks in Interferenceless Coded Aperture Correlation Holography [Invited]","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-01-13 11:58:29","doi":"10.21203/rs.3.rs-8443222/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-03-10T15:53:56+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-03T13:42:31+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"270671904760830330952540778654774301298","date":"2026-02-25T14:11:14+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-02-23T12:20:49+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-02-21T22:50:33+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"324803371035685037189018215376400158330","date":"2026-02-21T04:15:37+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"256442775033766395731700286422903727939","date":"2026-02-04T01:29:36+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-01-22T15:29:16+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-01-16T08:22:53+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"206767577126130605580223307264038292703","date":"2026-01-12T06:08:04+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"240850150366155973435250197533933855116","date":"2026-01-09T09:21:52+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2026-01-09T04:24:37+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-12-31T09:35:18+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-12-31T09:35:15+00:00","index":"","fulltext":""},{"type":"submitted","content":"Discover Imaging","date":"2025-12-24T13:37:02+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"discover-imaging","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"","sideBox":"Learn more about [Discover Imaging](https://link.springer.com/journal/44352)","snPcode":"44352","submissionUrl":"https://submission.springernature.com/new-submission/44352/3","title":"Discover Imaging","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Discover Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"540fa5ec-ffe6-4988-8eaa-2874ac0f79ba","owner":[],"postedDate":"January 13th, 2026","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-03-27T07:55:55+00:00","versionOfRecord":[],"versionCreatedAt":"2026-01-13 11:58:29","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8443222","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8443222","identity":"rs-8443222","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
