Experimental results of the multimodal system of microsphere beads. Phase imaging results: (a) phase hologram, (b) wrapped phase distribution, (c) 2-D unwrapped phase map, and (d) 3-D unwrapped phase distribution of a selected bead. FI results: (e) original focused image of the fluorescent beads, (f) fluorescent digital hologram obtained by moving the beads by $80\mu \mathrm{m}$ along the $z$ direction, and (g) reconstructed image of the fluorescent beads.
