In contrast to the conventional microscopes, the proposed RBL based device has a reconstruction depth of 1.5 mm, which is over 25 times of conventional microscopes. a Half image of the Measured hologram (MH) created with the RBL based SHS, and a half image of the modified MH, which has a numerically flattened background, and which is called Corrected Hologram (CH). b Three different reconstructions of the CH and one reconstruction of the MH. “zx” denotes the real axial target positions belonging to the reconstructions of both CH and MH. “z1” = −0.5 mm; “z2” = 0 mm (target is at the focal plane of the objective); “z3” = +1 mm
