Integrated intensity projections from a phase-gradient z-stack of beads in agarose gel (same sample as in Fig. 3). Panel b is a projection along the z-direction. Panels a,c are projections from ± 10° tilt directions (animation in Media 2 (906.5KB, AVI) ). Panels d–f are the same as the top row, but deblurred according to Eg. 18 (animation in Media 3 (1.7MB, AVI) ). The projections are generated from a 63×63×82 μm3 volume.
