The accurate modelling of the point spread function (PSF) is of paramount importance in
astronomical observations, as it allows for the correction of distortions and blurring caused …

Context. Next-generation large segmented mirror telescopes are expected to perform direct
imaging and characterization of Earth-like rocky planets, which requires contrast limits of …

Photon loss is the fundamental issue toward the development of quantum networks. To
circumvent loss quantum repeaters were proposed, which need high-performance quantum …

Adaptive optics normally concerns the feedback correction of phase aberrations. Such
correction has been of benefit in various optical systems, with applications ranging in scale …

The Roman Space Telescope will have the first advanced coronagraph in space, with
deformable mirrors (DMs) for wavefront control (WFC), low-order wavefront sensing and …

Polarized remote sensing imaging has attracted more attention in recent years due to its
wider detection information dimension compared to traditional imaging methods. However …

Context. To directly image rocky exoplanets in reflected (polarized) light, future space-and
ground-based high-contrast imagers and telescopes aim to reach extreme contrasts at close …

Integrated optical models allow for accurate prediction of the as-built performance of an
optical instrument. Optical models are typically composed of a separate ray trace and …

Low polarization systems have important advantages in many applications. Thanks to be
with seven free design parameters, three-mirror reflective systems have good potential to …

The Coronagraph Instrument of the Nancy Grace Roman Space Telescope (Roman
Coronagraph) will be capable of both total intensity and polarization measurements of …
