A conventional video-rate centimeter-range OCT requires an optical source with hundreds of kHz repetition rate and needs the support of broadband band detectors and electronics (\u0026gt;1 GHz). In this paper, a type of video-rate centimeter-range OCT system is proposed and demonstrated based on dual optical frequency combs by leveraging electro-optic modulators. The repetition rate difference between dual combs, i.e. the A-scan rate of dual-comb OCT, can be adjusted within 0~6 MHz. By down-converting the interference signal from optical domain to radio-frequency domain through dual comb beating, the down-converted bandwidth of the interference signal is less than 22.5 MHz which is at least two orders of magnitude lower than that in conventional OCT systems. A LabVIEW program is developed for video-rate operation, and the centimeter imaging range is proved by using 10 pieces of 1-mm thickness glass stacked as the sample. The effective beating bandwidth between two optical comb sources is 7 nm corresponding to ~108 comb lines, and the axial resolution of the dual-comb OCT is 157.8 µm. Dual optical frequency combs provide a promising solution to relax the detection bandwidth requirement in fast long-range OCT systems.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://figshare.com/collections/Video-rate_centimeter-range_optical_coherence_tomography_based_on_dual_optical_frequency_combs_by_electro-optic_modulators/4143335","contentUrl":null,"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":1,"citationCount":0,"citationsOverTime
