Abstract
Methods for obtaining a tomographic phase image of a specimen, either in transmission or in scatter. A specimen is illuminated by a temporally incoherent source and light collected in transmission or scattering is used to generate a scattered phase image of the specimen in multiple axial planes. The scattered field is solved for in wavevector space, and a derived instrument function is deconvolved to obtain specimen susceptibility in wavevector space. The specimen susceptibility is transformed to obtain a three-dimensional phase tomogram of the specimen.
