(a) Schematic diagram of our experimental setup. The aperture to object distance is much larger than the object to detector distance (z1~10 cm, z2<1mm). A shift of the aperture causes a demagnified shift of the object hologram formed at the detector plane, allowing sub-pixel hologram shifting. (b) Physical pixels captured in a single frame, here marked by bold borders, over imposed on the high-resolution pixel grid. This frame is shifted a distance of hk horizontally and vk vertically with respect to a reference frame.
