Quantum Limited Superresolution of Extended Sources in One and Two Dimensions

Sudhakar Prasad

We calculate the quantum Fisher information (QFI) for estimating, using a circular imaging aperture, the length of a uniformly bright incoherent line source with a fixed mid-point…

Point Spread Function Engineering for 3D Imaging of Space Debris using a Continuous Exact l0 Penalty (CEL0) Based Algorithm

Chao Wang, Raymond H. Chan, Robert J. Plemmons +1

We consider three-dimensional (3D) localization and imaging of space debris from only one two-dimensional (2D) snapshot image. The technique involves an optical imager that exploit…

Quantum Limited Source Localization and Pair Superresolution under Finite Emission Bandwidth

Sudhakar Prasad

Optically localizing a single quasi-monochromatic source to sub-diffractive precisions entails, in the photon-counting limit, a minimum photon cost that scales as the squared ratio…

Quantum limited super-resolution of an unequal-brightness source pair in three dimensions

Sudhakar Prasad

This paper extends our previous quantum Fisher information (QFI) based analysis of the problem of separating a pair of equal-brightness incoherent point sources in three dimensions…

Joint 3D Localization and Classification of Space Debris using a Multispectral Rotating Point Spread Function

Chao Wang, Grey Ballard, Robert Plemmons +1

We consider the problem of joint three-dimensional (3D) localization and material classification of unresolved space debris using a multispectral rotating point spread function (RP…

Novel Sparse Recovery Algorithms for 3D Debris Localization using Rotating Point Spread Function Imagery

Chao Wang, Robert Plemmons, Sudhakar Prasad +2

An optical imager that exploits off-center image rotation to encode both the lateral and depth coordinates of point sources in a single snapshot can perform 3D localization and tra…
