On-sky demonstration of second-stage wavefront control with a photonic lantern
Aditya R. Sengupta, Jordan Diaz, Matthew DeMartino +14
Ground-based direct imaging of exoplanets at high contrast requires precise correction of atmospheric turbulence using adaptive optics (AO). The planet-to-star contrast ratio at sm…
On-sky Demonstration of Subdiffraction-limited Astronomical Measurement Using a Photonic Lantern
Yoo Jung Kim, Michael P. Fitzgerald, Sébastien Vievard +18
Resolving fine details of astronomical objects provides critical insights into their underlying physical processes. This drives in part the desire to construct ever-larger telescop…
PIRATES -- a machine-learning framework for polarized, interferometric image reconstruction
Lucinda Lilley, Barnaby Norris, Peter Tuthill +13
Optical interferometric image reconstruction is a challenging, ill-posed optimization problem which usually relies on heavy regularization for convergence. Conventional algorithms…
Experimental and on-sky demonstration of spectrally dispersed wavefront sensing using a photonic lantern
Jonathan Lin, Michael P. Fitzgerald, Yinzi Xin +12
Adaptive optics systems are critical in any application where highly resolved imaging or beam control must be performed through a dynamic medium. Such applications include astronom…
