Abstract

The axial resolution of optical coherence tomography (OCT) is determined by the coherence length of the light source. We demonstrate for the first time high-resolution OCT of biological tissue using a halogen lamp as the light source for a low coherence interferometer. High-resolution OCT imaging with 3.5 μm resolution was performed successfully for onion and porcine skin, although the coherence light power for illumination of a sample is as small as 100 nW.
