Imaging or measurement methods and systems including methods and systems for finding the three-dimensional orientation and position of multiple dipole-like particles and single molecules, methods and systems for generating helical beams and helical spread functions, and methods and systems for super-resolution and super-localization of dense arrays of emitters.

Imaging or measurement methods and systems

Embodiments include methods, systems, and/or devices that may be used to image, obtain three-dimensional information from a scence, and/or locate multiple small particles and/or objects in three dimensions. A point spread function (PSF) with a predefined three dimensional shape may be implemented to obtain high Fisher information in 3D. The PSF may be generated via a phase mask, an amplitude mask, a hologram, or a diffractive optical element. The small particles may be imaged using the 3D PSF. The images may be used to find the precise location of the object using an estimation algorithm such as maximum likelihood estimation (MLE), expectation maximization, or Bayesian methods, for example. Calibration measurements can be used to improve the theoretical model of the optical system. Fiduciary particles/targets can also be used to compensate for drift and other type of movement of the sample relative to the detector.

High performance media suitable for recording with a blue laser is disclosed. The blue-sensitized holographic media provides greater dynamic range and higher sensitivity than previously disclosed blue-sensitized holographic media. These media can be used for diverse applications such as data storage where the articles provide denser data storage and more rapid hologram writing times or for optical waveguides where the articles provide greater optical confinement and more rapid manufacturing times.
