Joint optimization of wavefront sensing and reconstruction with automatic differentiation [PDF]
Astronomical Telescopes + Instrumentation, 2022 High-contrast imaging instruments need extreme wavefront control to directly image exoplanets. This requires highly sensitive wavefront sensors which optimally make use of the available photons to sense the wavefront.

Wavefront Reconstruction Using Two-Frame Random Interferometry Based on Swin-Unet
PhotonicsDue to its high precision, phase-shifting interferometry (PSI) is a commonly used optical component detection method in interferometers. However, traditional PSI, which is susceptible to environmental factors, is costly, with piezoelectric ceramic ...

Super-resolution wavefront reconstruction [PDF]
Astronomy & Astrophysics, 2022 Super-Resolution (SR) is a technique that seeks to upscale the resolution of a set of measured signals. SR retrieves higher-frequency signal content by combining multiple lower resolution sampled data sets.

Method for distortion correction of multi-layered surface reconstruction using time-gated wavefront sensing approach [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In order to estimate the multi-layer surface profile and to detect the inter-layer surfaces defects, gated wavefront sensing approach has been proposed in the previous works [1, 2].
