Abstract

From a practical point of view, single-shot phase microscopy systems have several hardware advantages in terms of deploying them for applications, e.g. at clinical sites. The problem of recovering full diffraction-limited phase information from single-shot image plane holograms is however not straightforward as the solution is not unique. Our work over the last several years shows that image sparsity ideas incorporated into hologram demodulation algorithms can effectively surpass several long-held limits on phase imaging performance in terms of resolution and accuracy. Our efforts in converting these algorithmic ideas into a microscope device and diagnostic application development will be covered briefly.
