{"doi":"10.1364/optcon.465713","title":"Application of a wavelength-swept laser for spectrally resolved wide-field near-infrared fluorescence imaging","abstract":"We propose the proof-of-concept of a novel method for wide-field spectrally resolved near-infrared fluorescence (NIRF) imaging using a wavelength-swept laser. The performance of our method is evaluated on a biotissue-like phantom bearing two inclusions, one filled with indocyanine green (ICG) dissolved in distilled water and the second one in dimethyl sulfoxide (DMSO). A near-infrared wavelength-swept laser covering wavelengths around the peak absorption of ICG was used. The difference in the absorption spectra of these two ICG solutions gives rise to an additional spectral contrast. The distinction between the emitted fluorescence light from the two different solutions is performed using a principal component analysis (PCA)-based method. Results show that the two different ICG solutions were successfully resolved using this approach. This technique can be a powerful method to simultaneously spatio-spectrally image multiple near-infrared fluorescence agents.","journal":"Optics Continuum","year":2022,"id":292052,"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":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9667,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":976228,"name":"Jaedu Cho","orcid":null,"position":1,"is_corresponding":false},{"id":424426,"name":"Maha Algarawi","orcid":"0000-0002-3367-1199","position":2,"is_corresponding":false},{"id":975733,"name":"Chang‐Seok Kim","orcid":"0000-0002-2811-8137","position":3,"is_corresponding":false},{"id":425391,"name":"Gültekin Gülşen","orcid":null,"position":4,"is_corresponding":false},{"id":424427,"name":"Farouk Nouizi","orcid":"0000-0001-5395-2505","position":0,"is_corresponding":true}],"reference_count":34,"raw_metadata":null,"created_at":"2026-07-19T00:30:42.221508Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
