Principles of reconstructing 3D RI tomograms of frog erythrocytes using ODT. (a) Schematic diagram of image acquisition process in ODT. (b) Experimental setup. C: collimator; DMD: digital micromirror device; TL: tube lens; M: mirror, CL: condenser lens; OL: objective lens, BS: beam splitter; P: polarizer. (c) 49 measured off-axis holograms and retrieved phase and amplitude maps. (d) Cross sections of the reconstructed RI tomogram from the phase and amplitude maps in (c).
