In the established methods, both the spatial and temporal coherence of light play a crucial role in determining the resolution of reconstructed object. We report lensless microscopy with a spatially extended white LED, a light source of low spatial and very low temporal coherence. The wave-field propagation between two parallel planes can be obtained using a convolution operation, where the convolution kernel depends on the object","authors_text":"Manjunatha Mahadevappa, Pranab Kumar Dutta, Sanjeev Kumar","cross_cats":["eess.IV","physics.app-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2020-02-09T14:19:05Z","title":"Lensless in-line holographic microscopy with light source of low spatio-temporal coherence"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2002.03369","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:fe6c11cd887ec0962731b2f560f12ef2d8f6394de26164585ba75eafb941767b","target":"record","created_at":"2026-07-05T01:48:25Z","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":"8207f52bd9e5c1c0237883298a3ad9478753e1212c4a9264b52cb3ca2494e151","cross_cats_sorted":["eess.IV","physics.app-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2020-02-09T14:19:05Z","title_canon_sha256":"8523be37e17763d58ead3083a90c1885d5cd659e2390f8c0bec19c8fbb661613"},"schema_version":"1.0","source":{"id":"2002.03369","kind":"arxiv","version":1}},"canonical_sha256":"9f9c945c71573a930b6e1cd53d1776d3a7db49275ae4fedbaf505dc9378590c3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9f9c945c71573a930b6e1cd53d1776d3a7db49275ae4fedbaf505dc9378590c3","first_computed_at":"2026-07-05T01:48:25.794754Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:48:25.794754Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U5uRQQ6ovlunIzhNqR5nMqk9HC5EV5T5UI6r1dz6T4rArTgkUDo8EUOHUG1OlnzPF9ComiAd1meFKH0sXFdfCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:48:25.795214Z","signed_message":"canonical_sha256_bytes"},"source_id":"2002.03369","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fe6c11cd887ec0962731b2f560f12ef2d8f6394de26164585ba75eafb941767b","sha256:6598eb5f1b9deafc0ae40b5c72fa1905f809ca7711234e86c05db5158def3787"],"state_sha256":"428b3e4d51b67ab157024a5a4505b76178a2d2fcd7cc2ce236db8f8dccaf46c1"}
