Six-pack holography and dynamic synthetic aperture superresolution (Conference Presentation)

Six-pack holography (6PH) is the first holographic imaging modality that is more spatial bandwidth efficient than on-axis holography. 6PH utilizes a low-coherence light source and a phase delay plate to enable the spatial multiplexing of six off-axis holograms without cross-talk between the six sample and six reference beams, and is thus capable of acquiring six off-axis holograms in a single camera exposure. We applied 6PH to synthetic aperture (SA) superresolution, and produced an SA capable of dynamically increasing the resolution by a factor of 1.62. 6PH presents a valuable general purpose technique for all holography applications and label-free imaging.
