We propose a novel interferometric method based on digital holography with low-coherence interferometry, the phase-shifting method, and the two-wavelength method. Low-coherence interferometry omits unwanted photons derived from multiple scattering. The phase-shifting method obtains the complex amplitude distribution of an object from several interference patterns. The two-wavelength method yields a surface profile without phase unwrapping from noisy interference signals. We demonstrate topographic imaging of an object in a light-scattering medium.
