a. illuminating the specimen through a condenser annulus that introduces a phase delay that is an integral multiple of π/2 with illuminating light characterized by a coherence length substantially shorter than 10 micrometers;\n
b. scanning a focus to a plurality of depths within the specimen;\n
c. spatially Fourier transforming light transmitted through the specimen at each of the plurality of depths;\n
d. temporally modulating at least one of the phase and amplitude of the spatial frequency components of the spatially transformed image to obtain interferograms at a plurality of relative phase offsets;\n
