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