Incoherent digital holographic system for 3-D FI. (a) Schematic representation of the common-path off-axis digital holographic setup. (b) The phase pattern displayed on the SLM, (c) focused image of the fluorescent beads, and an enlarged view of one bead is also shown sideways, (d) image obtained when the pattern shown in Fig. 1(b) displayed on the SLM, and an enlarged view of one bead is also shown sideways, (e) recorded fluorescent hologram obtained by moving the sample in the $z$ direction by $-80\mu \mathrm{m}$, (f) reconstructed image of the fluorescent beads, and (g) normalized intensity plot for the recorded and reconstructed selected fluorescence beads across the line AB, marked in (f).
