Photonic lantern nulling (PLN) is a method for enabling the detection and characterization of
close-in exoplanets by exploiting the symmetries of the ports of a mode-selective photonic …

The Space Coronagraph Optical Bench (SCoOB) is a high-contrast imaging testbed built to
demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuum …

Context. The differential optical transfer function (dOTF) is a model-independent image-
based wavefront sensor for measuring the complex pupil field (phase and amplitude). This …

The future Habitable Worlds Observatory aims to characterize the atmospheres of rocky
exoplanets around solar-type stars. The Vector Vortex Coronagraph (VVC) is a main …

The creation of a dark hole (DH) region in the science image for exoplanet direct detection
depends on deformable mirrors (DMs), where the imperfect control of DM limits the …

Coronagraphic instruments provide a great chance of enabling high contrast spectroscopy
for the pursuit of finding a habitable world. Future space telescope coronagraph instruments …

We present the preliminary design of GMagAO-X, the first-light high-contrast imager planned
for the Giant Magellan Telescope. GMagAO-X will realize the revolutionary increase in …

Direct imaging of exoplanets relies on complex wavefront sensing and control architectures.
In addition to fast adaptive optics systems, most of the future high-contrast imaging …

Extreme wavefront correction is required for coronagraphs on future space telescopes to
reach 10-8 or better starlight suppression for the direct imaging and characterization of …
