Query: Particle Tracking and Extended Object Imaging by Interferometric Super
  Resolution Microscopy   An interferometric fluorescent microscope and a novel theoretic image
reconstruction approach were developed and used to obtain super-resolution
images of live biological samples and to enable dynamic real time tracking. The
tracking utilizes the information stored in the interference pattern of both
the illuminating incoherent light and the emitted light. By periodically
shifting the interferometer phase and a phase retrieval algorithm we obtain
information that allow localization with sub-2 nm axial resolution at 5 Hz.
