Abstract

We demonstrate that the sidelobes of a Bessel function generated by an axicon were suppressed by more than 20 dB over 5 mm depth of focus in a Fourier domain optical coherence tomography using a single mode fiber. We also show a rotational image in biological tubular in vivo samples with 2.5 μm axial resolution, 8 μm lateral resolution, and 5 mm depth of focus using a custom-designed axicon.
