Active Adjustment of the Subreflector Shape for the Large Dual-Reflector Antenna
Micromachines, 2023 A shape adjustment method for subreflectors based on minimizing the residual wavefront error of the large dual-reflector antenna is presented. This method is used to compensate for the antenna structural deformation caused by environment loading.

Minimum change in spherical aberration that can be perceived
Biomedical Optics Express, 2016 It is important to know the visual sensitivity to optical blur from both a basic science perspective and a practical point of view. Of particular interest is the sensitivity to blur induced by spherical aberration because it is being used to increase depth of focus as a component of a presbyopic solution.
