Experimental validation of photonic lantern imaging and wavefront sensing performance
Aditya R. Sengupta, Vincent Chambouleyron, Jordan Diaz +15
Photonic lanterns (PLs) are fiber-based waveguides that are capable of focal-plane wavefront sensing while simultaneously directing light to downstream science instruments. The opt…
The Focal-plane Actualized Shifted Technique Realized for a Shack Hartmann Wavefront Sensor (fastrSHWFS)
Benjamin L. Gerard, Aaron Lemmer, Bautista R. Fernandez +6
Astronomical adaptive optics (AO) is a critical approach to enable ground-based diffraction-limited imaging and high contrast science, with the potential to enable habitable exopla…
Photonic lantern wavefront reconstruction in a multi-wavefront sensor single-conjugate adaptive optics system
Aditya R. Sengupta, Jordan Diaz, Benjamin L. Gerard +6
Exoplanet direct imaging using adaptive optics (AO) is often limited by non-common path aberrations (NCPAs) and aberrations that are invisible to traditional pupil-plane wavefront…
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…
Deformable mirror-based pupil chopping for exoplanet imaging and adaptive optics
Javier Perez Soto, Cesar Laguna, Benjamin L. Gerard +3
Due to turbulence in the atmosphere images taken from ground-based telescopes become distorted. With adaptive optics (AO) images can be given greater clarity allowing for better ob…
First laboratory demonstration of real-time multi-wavefront sensor single conjugate adaptive optics
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +1
Exoplanet imaging has thus far enabled studies of wide-orbit (10 AU) giant planet (2 Jupiter masses) formation and giant planet atmospheres, with future 30 meter-class Extrem…
