One of the key noise sources that currently limits high-contrast imaging observations for exoplanet detection is quasi-static speckles. Quasi-static speckles originate from slowly evolving non-common path aberrations (NCPA). The purpose of this work is to present a proof-of-concept on-sky demonstration of spatial Linear Dark Field Control (LDFC). The ultimate goal of LDFC is to stabilize the point spread function (PSF) by addressing NCPA using the science image as additional wavefront sensor…

Laboratory demonstration of real-time focal plane wavefront control of residual atmospheric speckles

Abstract. Current and future high contrast imaging instruments aim to detect exoplanets at closer orbital separations, lower masses, and/or older ages than their predecessors. However, continually

High contrast imaging at the photon noise limit with self-calibrating WFS/C systems

TLDR
A path toward designing HCI systems capable of calibrating residual starlight at the fundamental contrast limit imposed by photon noise is discussed and the value of deploying multiple high-efficiency wavefront sensors covering a wide spectral range and spanning multiple optical locations is highlighted.

Laboratory demonstrations of EFC and spatial LDFC on Subaru/SCExAO

To directly image and characterize exoplanets, many developments of high-contrast imaging (HCI) systems are ongoing for current ground-based telescopes as well as future extremely large telescopes

TLDR
The design process, development, commissioning, on-sky performance, and first scientific results of all commissioned vAPPs are reviewed and perspectives for future developments and applications are concluded.

High contrast imaging at the photon noise limit with WFS-based PSF calibration

Speckle Noise is the dominant source of error in high contrast imaging with adaptive optics system. We discuss the potential for wavefront sensing telemetry to calibrate speckle noise with sufficient

SCExAO: a testbed for developing high-contrast imaging technologies for ELTs

TLDR
A live demonstration of the SCExAO capabilities is presented as a host testbed for the remote collaborators to test and deploy the new WFS&C concepts or algorithms and several high-contrast imaging technologies that are under development or that have already been demonstrated on-sky.
