摘要：
We present a 3D imaging system for simultaneously imaging the distributions of refractive index and optical absorption using a transmission Fourier-domain low-coherence interferometer. The forward-scattering light travelling through a sample interferes with a reference light beam. The projections of refractive index and optical absorption within the sample are calculated from measured interference fringes. We acquire the projections at sufficient angular views and reconstruct the distributions of refractive index and optical absorption using the filter back-projection algorithm. The proposed method is experimentally verified by using a plastic tube phantom.
