Dynamic aberration correction for multiharmonic microscopy.
Optics Letters, 2009 International audienceWe demonstrate image-based aberration correction in a third-harmonic generation (THG) microscope. We describe a robust, mostly sample-independent correction scheme relying on prior measurement of the influence of aberration modes ...

Active Alignment of Large-Aperture Space Telescopes for Optimal Ellipticity Performance
Sensors, 2023 Ellipticity performance of space telescopes is important for exploration of dark matter. However, traditional on-orbit active optical alignment of space telescopes often takes “minimum wavefront error across the field of view” as the correction goal, and
