Spectrally encoded flow cytometry (SEFC) is a promising technique for noninvasive in vivo microscopy of blood cells. Here, we introduce a novel SEFC system for label-free confocal imaging of blood cells flowing at velocities of up to 10mm/s within 65 μm-diameter vessels. The new system employs interferometric Fourier-domain detection and a high-speed wavelength-swept source, allowing 100 kHz line rate, sufficient for sampling the rapidly flowing cells 80 μm below the tissue surface. The large data sets obtained by this technique would improve diagnosis accuracy, reduce imaging time, and open new possibilities for noninvasive monitoring of blood in patients.
