Quantum limited imaging of a nanomechanical resonator with a spatial mode sorter
Morgan Choi, Christian Pluchar, Wenhua He +2
We explore the use of a spatial mode sorter to image a nanomechanical resonator, with the goal of studying the quantum limits of active imaging and extending the toolbox for optome…
Adaptive Super-Resolution Imaging Without Prior Knowledge Using a Programmable Spatial-Mode Sorter
Itay Ozer, Michael. R. Grace, Pierre-Alexandre Blanche +1
We consider an imaging system tasked with estimating the angular distance between two incoherently-emitting, identically bright, sub-Rayleigh-separated point sources, without any p…
Experimental Demonstration of a Quantum-Optimal Coronagraph Using Spatial Mode Sorters
Nico Deshler, Itay Ozer, Amit Ashok +1
Deep sub-diffraction exoplanet discovery currently lies beyond the reach of state-of-the-art direct imaging coronagraphs, which typically have an inner working angle larger than th…
Imaging-based Quantum Optomechanics
Christian M. Pluchar, Wenhua He, Jack Manley +3
In active imaging protocols, information about an object is encoded into the spatial mode of a scattered photon. Recently the quantum limits of active imaging have been explored wi…
Optimum classical beam position sensing
Wenhua He, Christos N. Gagatsos, Dalziel J. Wilson +1
Beam displacement measurements are widely used in optical sensing and communications; however, their performance is affected by numerous intrinsic and extrinsic factors including b…
