a Cross-sectional OCT image of the retinal phantom. Ch1, the first microfluidic channel, mimics superficial vessels. Ch2 and Ch3 are the second and third microfluidic channels and replicate the deep and choroidal vessels, respectively. Scale bar is 100 μm. b Result of the axial resolution measurement from the line spread function (yellow line) in (a) after zero-padding from the original axial resolution measurement data in Supplementary Data 2.
