{"doi":"10.1364/ol.430915","title":"Phase-corrected buffer averaging for enhanced OCT angiography using FDML laser","abstract":"Megahertz-rate optical coherence tomography angiography (OCTA) is highly anticipated as an ultrafast imaging tool in clinical settings. However, shot-noise-limited sensitivity is inevitably reduced in high-speed imaging systems. In this Letter, we present a coherent buffer averaging technique for use with a Fourier-domain mode-locked (FDML) laser to improve OCTA contrast at 1060 nm MHz-rate retinal imaging. Full characterization of spectral variations among the FDML buffers and a numerical correction method are also presented, with the results demonstrating a 10-fold increase in the phase alignment among buffers. Coherent buffer averaging provided better OCTA contrast than the conventional multi-frame averaging approach with a faster acquisition time.","journal":"Optics Letters","year":2021,"id":188512,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":16,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9587,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":750399,"name":"Mahsa Siadati","orcid":null,"position":1,"is_corresponding":false},{"id":749628,"name":"Jun Song","orcid":"0009-0000-5875-484X","position":2,"is_corresponding":false},{"id":286553,"name":"Da Ma","orcid":"0000-0002-3542-7798","position":3,"is_corresponding":false},{"id":525574,"name":"Yifan Jian","orcid":"0000-0001-7988-7385","position":4,"is_corresponding":false},{"id":324262,"name":"Mirza Faisal Beg","orcid":"0000-0001-6706-8630","position":5,"is_corresponding":false},{"id":525573,"name":"Marinko V.
