Optical microscopy with extended depth of field

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1983
Abstract A method is described that allows the depth of field in optical microscopy to be extended, in principle without limit, while high-resolution, diffraction-limited imaging is retained. Experimentally, an extension of more than two orders of magnitude has been achieved.

Optical correlator with extended depth of field

Optics Communications, 1981
Abstract Preprocessing with a Fabry-Perot etalon in the image plane of an optical correlator is used to extend the depth of field of the instrument without reducing its selectivity. Experimental results are compared with the output of a classical correlator as well as with theory.

Extended Depth-of-Field Intraocular Lenses

2019
Extended depth-of-focus (EDOF) optical profiles are a new optical design that is currently considered as an attractive alternative to accommodative and multifocal intraocular lenses (IOLs). Currently several optical principles might be utilized to indicate the physical mechanism of light bundling and are applied to EDOF IOLs—diffractive and/or ...
