Calculating Point Spread Functions: Methods, Pitfalls and Solutions

Ratsimandresy Holinirina Dina Miora, Erich Rohwer, Martin Kielhorn +3

The knowledge of the exact structure of the optical system PSF enables a high-quality image reconstruction in fluorescence microscopy. Accurate PSF models account for the vector na…

A table of some coherency matrices, coherency matrix factors (CMFs), and their respective Mueller matrices

Colin J. R. Sheppard, Aymeric Le Gratiet, Alberto Diaspro

Many books on polarization give tables of Mueller matrices. Here we give a table of Mueller matrices M, coherency matrices C, and coherency matrix factors F for different polarizat…

Label-free three-dimensional (3D) structural imaging in live cells using intrinsic optical refractive index

Chen Liu, Michael Malek, Ivan K. H. Poon +10

Here we report a method for visualization of volumetric structural information of live biological samples with no exogenous contrast agents. The process is made possible through a…

Spectral decomposition of the Mueller matrix: A geometrical model

Colin J. R. Sheppard

An arbitrary Mueller matrix can be decomposed into a sum of up to four deterministic Mueller-Jones matrices, with strengths given by the eigenvalues of an associated Hermitian matr…

The Green-function transform and wave propagation

Colin J. R. Sheppard, Shan Shan Kou, Jiao Lin

Fourier methods well known in signal processing are applied to three-dimensional wave propagation problems. The Fourier transform of the Green function, when written explicitly in…

Optical Photon Reassignment Microscopy (OPRA)

Stephan Roth, Colin J. R. Sheppard, Kai Wicker +1

To enhance the resolution of a confocal laser scanning microscope the additional information of a pinhole plane image taken at every excitation scan position can be used [C. J. R.…
