Paper Abstract

We report on ultrahigh-resolution Optical Coherence Tomography (OCT) using white-light interference microscopy. The experimental setup is based on a Linnik interferometer illuminated by a tungsten halogen lamp. Tomographic images in the en face orientation are calculated by combination of images recorded by a silicon CCD camera. Axial resolution of 0.8 μm is achieved due to the short coherence length of the source and the compensation of dispersion mismatch in the interferometer arms. Transverse resolution of 1.6 μm is obtained by using relatively high numerical aperture microscope objectives. A nearly shot-noise limited detection sensitivity of 90 dB is achieved with 4s acquisition time. Images of the Xenopus Laevis tadpole are presented.
