Download Super-Resolved Imaging: Geometrical and Diffraction by Alex Zlotnik, Zeev Zalevsky, David Mendlovic, Jonathan PDF

By Alex Zlotnik, Zeev Zalevsky, David Mendlovic, Jonathan Solomon (auth.), Zeev Zalevsky (eds.)

In this short we overview a number of methods that offer great resolved imaging, overcoming the geometrical hassle of the detector in addition to the diffraction results set by way of the F variety of the imaging lens. with a purpose to receive the large resolved enhancement, we use spatially non-uniform and/or random transmission constructions to encode the picture or the aperture planes. the specified answer superior photos are bought via post-processing deciphering of the captured data.

The CTF coding mask, G~ðnÞ, which is attached to it. 16) where gg indicates the object obtained at the sensor plane in an ideal system (without any other aberrations). The sensor samples only magnitudes of the image. 17) In order not to have information loss, system output, Oi , should be real and nonnegative; this will enable retrieval of output directly from Ii (which is actually the squared absolute of Oi ). In order to ensure direct retrieval of the object, gg in full resolution, both the coding mask and the image must be real and nonnegative.

In order to ensure direct retrieval of the object, gg in full resolution, both the coding mask and the image must be real and nonnegative. Since real images have no negative values, therefore it is left to deal only with the 46 A. Zlotnik et al. coding mask. The coding mask must have a Fourier transform that is real and nonnegative. 3). Below an example for a suitable coding mask is presented: Let us choose a coding mask composed of an infinite train of delta-functions in the space domain, each impulse is spaced by D from adjacent impulses.
