However, the infrared 3D imaging at low-light levels is still challenging due to the deficiency of sensitive and fast MIR sensors. Here we propose and implement a MIR time-of-flight imaging system that operates at single-photon sensitivity and femtosecond timing resolution. Specifically, back-scattered infrared photons from a scene are optically gated by delay-controlled ultrashort pump pulses thro","authors_text":"E Wu, Heping Zeng, Jianan Fang, Kun Huang, Ming Yan","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2026-05-29T00:50:39Z","title":"Mid-infrared single-photon 3D imaging"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.30702","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:e0effaba4835dbdc2e6c8ffec22aeda9f5a4bbfe091c97138ff2f060fe9c95e9","target":"record","created_at":"2026-06-01T01:03:09Z","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":"92c6f131b3240cfe50c5afef3775484b5a56f1b589ebbf68374af1b2f25da4e3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2026-05-29T00:50:39Z","title_canon_sha256":"82cbc5e8945134d648289a578eaccaf3a547b3a2aeddb405a134297186f7ae21"},"schema_version":"1.0","source":{"id":"2605.30702","kind":"arxiv","version":1}},"canonical_sha256":"04864a0ae600c93fb4a5acaca770d43bca3448924f9a94242cf7400b5ae043f1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"04864a0ae600c93fb4a5acaca770d43bca3448924f9a94242cf7400b5ae043f1","first_computed_at":"2026-06-01T01:03:09.338727Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-01T01:03:09.338727Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gGSApRB2BQ90JSxqo2fFs18pQXVlhKsXt4HKtv/BKzVET7n2+sD6Bpionjy2xcjZz3xuuRXtH8XWNHr/ElrdCg==","signature_status":"signed_v1","signed_at":"2026-06-01T01:03:09.339455Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.30702","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e0effaba4835dbdc2e6c8ffec22aeda9f5a4bbfe091c97138ff2f060fe9c95e9","sha256:6d5f3f6f030b3cc385a514810f6b095f96c2829bb14e90ada3730bd628c4d4f3"],"state_sha256":"7c8db0eb71e52e32255ab0a4a07029a309df0984120f4dafb73c50e311404baa"}
