Adaptive optics techniques have been developed over the past half century and routinely
used in large ground-based telescopes for more than 30 years. Although this technique has …

As we look to the next generation of adaptive optics systems, now is the time to develop and
explore the technologies that will allow us to image rocky Earth-like planets; wavefront …

输出是激光自适应光学技术的一项重要目标. 自适应光学主要是利用波前传感器和波前校正器来 …

We present a novel formulation of closed-loop adaptive optics (AO) control as a multi-agent
reinforcement learning (MARL) problem in which the controller is able to learn a non-linear …

Current and future high-contrast imaging instruments require extreme adaptive optics
systems to reach contrasts necessary to directly imaged exoplanets. Telescope vibrations …

We propose a novel control approach that combines offline supervised learning to address
the challenges posed by non-linear phase reconstruction using unmodulated pyramid …

Focal plane wavefront sensing (FPWFS) is appealing for several reasons. Notably, it offers
high sensitivity and does not suffer from non-common path aberrations (NCPAs). The price …

The contrast performance of current extreme adaptive optics (XAO) systems can be
improved by adding a second AO correction stage featuring its own wavefront sensor (WFS) …

The time-delay problem, which is introduced by the response time of hardware for
correction, is a critical and non-ignorable problem of adaptive optics (AO) systems. It will …

We apply a U-Net-based convolutional neural network (NN) architecture to the problem of
predictive adaptive optics (AO) for tracking and imaging fast-moving targets, such as …
