Abstract
An imaging system is provided. The imaging system includes a point spread function (PSF) module producing a diffraction-limited image of a sample. A convolution module performs convolution of the diffraction-limited image with a first image of a focal spot having a first wavelength to produce a first simulated image. The convolution also performs convolution of the diffraction-limited image with a second image of a focal ring having a second wavelength to produce a second simulated image. A difference module subtracts said first simulated image and said second simulated image to produce said high resolution composite image.
