Abstract

We demonstrate ultrahigh resolution optical coherence tomography using the continuum generation in an air-silica microstructure fiber. A broadband OCT system was developed, supporting a bandwidth of 370 nm at 1.3 μm center wavelength. We achieved longitudinal resolutions of 2.5 μm in air, or ∼2 μm in tissue. This is to our knowledge the highest longitudinal OCT resolution demonstrated at this wavelength range and the first application of this new light source for OCT. We will also describe the application of this technique for imaging biological tissue in vivo.
