Super-resolution in confocal scanning microscopy: generalized inversion formulae

It was shown in previous papers that the resolution of a confocal scanning microscope can be significantly improved by measuring, for each scanning position, the full diffraction image and by inverting these data to recover the value of the object at the confocal point. In the present work, the authors generalize the data inversion procedure by allowing, for reconstructing the object at a given point, to make use of the data samples recorded at other scanning positions. This leads them to a family of generalized inversion formulae, either exact or approximate. Some previously known formulae are re-derived here as special cases in a particularly simple way.

Broadband pulse propagation with electromagnetically induced transparency: Splitting of adiabatic and nonadiabatic components

The propagation of a broadband pulse through a dense resonant medium with a narrow transparency window is considered. We show that the pulse splits into a slowly propagating adiabatic part and a fast nonadiabatic part. © 2005 Optical Society of America.
