Using a diodepumped Ti:sapphire crystalline fiber with a high numerical aperture, spatially-incoherent broadband emission can be generated with high radiance. With two modes of different spatial coherence settings, either deeper penetration depth or higher B-scan rate can be achieved. In a wide-field illumination mode, the system functions like FF-OCT with partially coherent illumination to improve the penetration depth. In a strip-field illumination mode, a compressed field is generated on the sample, and a low-speckle B-scan can be acquired by compounding pixel lines within. ? 2021 Optical Society of America.SapphireTomographyBroadband emissionCrystalline fibersFull-field optical coherence tomographiesHigh numerical aperturesPartially coherent illuminationSpatial coherenceSpatially coherent illuminationSystem functionsOptical tomographymelaninArticleB scancoating uniformitycoherent illumination modedata analysis softwarehumanilluminationimage analysisimage qualitykeratinocytelight related phenomenameasurement accuracymethodologymicrovascular densitymirau type full field optical coherence tomographynormal distributionnumeracynumerical apertureoptical coherence tomographyopticspupilrefraction indexscintiscanningsensitivity analysisskinskin penetrationspatial orientationspectral sensitivitystrip field illumination mode[SDGs]SDG3journal article10.1364/BOE.4226222-s2.0-85105293531
