In this Letter, we report for the first time (to our knowledge) in-vivo volumetric optical coherence microscopy images of skin epidermal cells. We achieved micrometer-class resolution, laterally and axially, with an acquisition speed of A-scans/s and over sensitivity to a depth of by employing a custom, liquid-lens-based, dynamic-focusing objective, a broadband light source, and a custom, astigmatism-corrected Czerny–Turner spectrometer with a high-speed complementary metal-oxide-semiconductor camera.
