3D position localization in detector-limited systems

3D point-spread functions can be shaped to increase accuracies over a 3D volume. In the detector-limited regime, the gain in accuracy occurs in all three dimensions throughout the axial range of interest. The PSF is shaped as a double-helix, resulting in a system with fundamentally better 3D localization-accuracies than standard-PSF systems, capable of achieving single-image sub-nanometer accuracies.
