Welcome to the psf-generator library!
This library implements various physical models that compute the point spread function (PSF) of optical microscopes. PSF characterizes the response of an imaging system to a point source and is crucial for tasks such as deconvolution, correction of aberrations, and characterization of the system.
We classify these models in two types---scalar or vectorial--- and in both cases the PSF integral can be computed in Cartesian or spherical coordinate systems. This results in the following four propagators
| Name of propagator | Other names |
|---|---|
ScalarCartesianPropagator |
simple/scalar Fourier model |
ScalarSphericalPropagator |
Kirchhoff model |
VectorialCartesianPropagator |
vectorial Fourier model |
VectorialSphericalPropagator |
Richards-Wolf model |
