Near-null interferometry using an aspheric null lens generating a broad range of variable spherical aberration for flexible test of aspheres

open access: goldOptics Express, 2018
A null lens moving back and forth relative to a point source can generate variable spherical aberration for flexible test of aspheres. Different from the previous methods, variable spherical aberration null theory was developed by us to optimize the null

Minimum change in spherical aberration that can be perceived. [PDF]

open access: yesBiomed Opt 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 ...
