An apparatus and method for obtaining depth-resolved spectra for the purpose of determining the size of scatterers by measuring their elastic scattering properties. Depth resolution is achieved by using a white light source in a Michelson interferometer and dispersing a mixed signal and reference fields....http://www.google.ca/patents/USRE42497?utm_source=gb-gplus-sharePatent USRE42497 - Fourier domain low-coherence interferometry for light scattering spectroscopy apparatus and method
