title: Optical tomographic microscope for quantitative imaging of phase objects.
abstract: We describe a tomographic microscope, for imaging phase objects, that makes use of the transport-of-intensity equation to estimate the phase of the transmitted light through the object. The wave-front data from optical fibers are reconstructed with an algorithm that incorporates correction for the ray bending. The reconstructed refractive-index cross sections of the fibers are found to be in agreement with the available values specified in the catalogs.
