2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Approaches to lowering the cost of large space telescopes
Ewan S Douglas, Greg Aldering, Greg W. Allan +26
New development approaches, including launch vehicles and advances in sensors, computing, and software, have lowered the cost of entry into space, and have enabled a revolution in…
Integrated coronagraphy and wavefront sensing with the PIAACMC
Sebastiaan Y. Haffert, Jared R. Males, Olivier Guyon
Uncorrected wavefront errors create speckle noise in high-contrast observations at small inner-working angles. These speckles can be sensed and controlled by using coronagraph inte…
Reaching the fundamental sensitivity limit of wavefront sensing on arbitrary apertures with the Phase Induced Amplitude Apodized Zernike Wavefront Sensor (PIAA-ZWFS)
Sebastiaan Y. Haffert, Jared R. Males, Olivier Guyon
In the last two decades many people have been searching for the optimal wavefront sensor as it can boost the performance of high-contrast imagining by orders of magnitude on the EL…
GMagAO-X: A First Light Coronagraphic Adaptive Optics System for the GMT
Maggie Kautz, Jared R. Males, Laird M. Close +17
GMagAO-X is a visible to NIR extreme adaptive optics (ExAO) system that will be used at first light for the Giant Magellan Telescope (GMT). GMagAO-X is designed to deliver diffract…
Using the Gerchberg-Saxton algorithm to reconstruct non-modulated pyramid wavefront sensor measurements
Vincent Chambouleyron, Aditya Sengupta, Maïssa Salama +9
Adaptive optics (AO) is a technique to improve the resolution of ground-based telescopes by correcting, in real-time, optical aberrations due to atmospheric turbulence and the tele…
