It therefore grants access to superficial layers only. Recently developed techniques use scattered photons for imaging by exploiting angular correlations in transmitted light and could potentially increase imaging depths. But those correlations (`angular memory effect') are of very short range and, in theory, only present behind and not inside scattering media. From measurements on neural tissues and complementary simulations, we find that strong forward scattering in biological t","authors_text":"Jacopo Bertolotti, Jean-Francois L\\'eger, Laurent Bourdieu, Sam Schott, Sylvain Gigan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-02-01T15:00:33Z","title":"Characterization of the angular memory effect of scattered light in biological tissues"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.00270","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:1edb765310633284a1612e0ad5de3725d76046b537dbc3f105b23805450be4bc","target":"record","created_at":"2026-05-18T02:03:34Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"2e7d0aae9da8df2dbaf14aaafc8aa5a92625d95fcb80888ffd23ce1970d27478","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-02-01T15:00:33Z","title_canon_sha256":"08c20c24c61d2fe97868969859aff90e009f9ed552adccdb20f864799ceba26d"},"schema_version":"1.0","source":{"id":"1502.00270","kind":"arxiv","version":1}},"canonical_sha256":"81e9ecd69a28b8dea07cd2a57521c3f1cc28c9f0a03f58167f98c54295342f30","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"81e9ecd69a28b8dea07cd2a57521c3f1cc28c9f0a03f58167f98c54295342f30","first_computed_at":"2026-05-18T02:03:34.489291Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:03:34.489291Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cTay4rMaeMRjV76PBTGLfkhNXP0AgMFuk2WZCxjZVw/7WXFZee34dCnR2+6sBe+er0PmsC29I5E/fXKlHDz3CA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:03:34.489893Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.00270","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1edb765310633284a1612e0ad5de3725d76046b537dbc3f105b23805450be4bc","sha256:203605ac0c6bd4727e61fb851f7edaf9bef0d69d395b8d0d8d28658c551eaac2"],"state_sha256":"96c01c44bda1231a0dbd2f6388f8b8bb787b69044fe11098305e5706d94c5928"}
