Off-axis compressed holographic microscopy in low
... Off-axis holography is well-suited to dim light imaging. Shot-noise sensitivity in high optical gain regime can be achieved with few simple setup conditions [1]. Holographic measurements are made in dual domains, where each pixel exhibits spatially dispersed (i.e. multiplexed) information from the o ...
