A Michelson-type spectral interferometer that uses a common beam path for the reference and the sample arms is described. This optical arrangement is more compact and stable than the more commonly used dual-arm interferometer and is well suited for frequency-domain optical coherence tomography of biological samples. With a 16-bit CCD camera, the instrument has sufficient dynamic range and resolution for imaging to depths of 2 mm in scattering biological materials. Images obtained with this spectral interferometer are presented, including cross-sectional images in a Xenopus laevis tadpole.

  10. Killed tadpoles were used to comply with National Institutes of Health regulations regarding the use of live, vertebrate animals. (We do not have approval for experimentation that uses live vertebrates.) This SI method should be as applicable to live, in vivo measurements as time-domain OCT, although this remains to be demonstrated.
