Corkscrew point spread function for far-field three-dimensional nanoscale localization of pointlike objects.
We describe the corkscrew point spread function (PSF), which can localize objects in three dimensions throughout a 3.2 μm depth of field with nanometer precision. The corkscrew PSF rotates as a function of the axial (z) position of an emitter. Fisher information calculations show that the corkscrew PSF can achieve nanometer localization precision with limited numbers of photons. We demonstrate ...
متن کاملOne-dimensional iterative algorithm for three-dimensional point-spread function engineering.
We present a new method with which to binarize pupil filters designed to control the three-dimensional irradiance distribution in the focal volume of an optical system. The method is based on a one-dimensional iterative algorithm, which results in efficient use of computation time and in simple, easy to fabricate binary filters. An acceptable degree of resemblance between the point-spread funct...
متن کاملThree-dimensional point spread function model for line-scanning confocal microscope with high-aperture objective.
Point Spread Function (PSF) modelling is an important task in image formation analysis. In confocal microscopy, the exact PSF is rarely known, thus one has to rely on its approximation. An initial estimation is usually performed experimentally by measuring fluorescent beads or analytically by studying properties of the optical system. Yet, fluorescent line-scanning confocal microscopes are not ...
متن کاملThree-dimensional point distribution models for tubular objects
Landmark based statistical shape models are becoming increasingly popular in medical image analysis. These models require a set of training shapes in which corresponding landmarks are indicated. If a limited number of training shapes is available while a large number of landmarks is needed to describe a shape properly, a model based on observations in the training set alone may be too restricte...
متن کاملCorrecting field-dependent aberrations with nanoscale accuracy in three-dimensional single-molecule localization microscopy.
The localization of single fluorescent molecules enables the imaging of molecular structure and dynamics with subdiffraction precision and can be extended to three dimensions using point spread function (PSF) engineering. However, the nanoscale accuracy of localization throughout a 3D single-molecule microscope's field of view has not yet been rigorously examined. By using regularly spaced subd...
