We here show experimental applications of the technique for characterising both refractive and reflective optical components. These fast and accurate X-ray at-wavelength metrology methods can assist the manufacture of X-ray optics that transport X-ray beams with minimum amount of wavefront distortion. We also recall how such methods can facilitate online optimization of active optics.","authors_text":"Eric Ziegler, Pierre Piault, Rafael Celestre, Raymond Barrett, Ruxandra Cojocaru, Sebastien Berujon, Thomas Roth","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2019-12-03T02:10:35Z","title":"X-ray optics and beam characterisation using random modulation: Experiments"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1912.05432","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:b0abfd38b1e41b056afc54a1e222733501f9c0ca21308ae8706fd94ae9a54f63","target":"record","created_at":"2026-07-05T00:42:43Z","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":"fd19d31dae75a9355b206afd8658ccd034e865f1acc3b7ef345e5494a7c4b7e5","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2019-12-03T02:10:35Z","title_canon_sha256":"f02b0601138eee6115fb48df73a95d00622bbd4e836c0c7b0e5b16c7f33adfa3"},"schema_version":"1.0","source":{"id":"1912.05432","kind":"arxiv","version":1}},"canonical_sha256":"4ebb39d27a997d7873f2573e63a1c97550c2b332e6f8a9b2bf87f1fccf3b582b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4ebb39d27a997d7873f2573e63a1c97550c2b332e6f8a9b2bf87f1fccf3b582b","first_computed_at":"2026-07-05T00:42:43.288661Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:42:43.288661Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ir2HQ/caRxiO0pMUgE0OTo7VV64YatDYd0nWdL6RFuYxOYbzOV3tVBpHwM7fmsomqlJjMHcoH6YlT/wxEimkBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:42:43.289068Z","signed_message":"canonical_sha256_bytes"},"source_id":"1912.05432","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b0abfd38b1e41b056afc54a1e222733501f9c0ca21308ae8706fd94ae9a54f63","sha256:4ef77f71553edc01699eff1272f9034ad1e0f23cc85571b4da70e931b4e67fe9"],"state_sha256":"ff5cce9075784025c68813b8dc022ceeb7135cbb50914727514383c02887508f"}
