Multiframe blind deconvolution of infinite-extent objects
William C. van Kampen,Richard G. Paxman +1 more
- 03 Nov 1998
TL;DR: In this paper, a generalization of multi-frame blind deconvolution to accommodate objects that extend beyond the sensor field-of-view (FOV) is presented. But the generalization is limited to the case where the object has a finite extent that is often entirely contained within the FOV.

Speckle image reconstruction of the adaptive optics solar images
Libo Zhong,Yu Tian,Changhui Rao +2 more
TL;DR: Speckle image reconstruction, in which the speckle transfer function (STF) is modeled as annular distribution according to the angular dependence of adaptive optics (AO) compensation and the individual STF in each annulus is obtained by the corresponding Fried parameter calculated from the traditional spectral ratio method, is used to restore the solar images corrected by AO system.

Optics of a granular imaging system (i.e. “orbiting rainbows”)
TL;DR: In this article, the authors present some ideas for the optics and imaging aspects of granular spacecraft, which are complex systems composed of a spatially disordered distribution of a large number of elements, for instance a cloud of grins in orbit.

Cramer-Rao bound and phase-diversity blind deconvolution performance versus diversity polynomials
Jean J. Dolne,Harold B. Schall +1 more
TL;DR: It is shown that, in certain cases, defocus diversity may yield a higher Cramer-Rao lower bound (CRLB) than some other diversity phase functions.

Application of the Richardson-Lucy algorithm to the deconvolution of two-fold probability density functions
TL;DR: In this article, the Richardson-Lucy algorithm is used to deconvolve a set of images which are grey level representations of slices of two-fold probability density functions (PDFs) computed from the one-dimensional signal obtained with the ESO slit scanning infrared specklograph.
