Forward and inverse problems for symmetric starbursts
Abstract:
Visual starbursts are images perceived by people watching a bright light source with a dilated pupil. They are generated by the optical aberrations of a person's eye. The problem of starbursts is considered for two families of symmetric aberration functions. The first is homogeneous polynomials, and the second is aberration functions that are invariants under rotation by 2π/q for any integer q. A complete geometrical characterization of the starbursts is given in both cases. The theory is used to solve the inverse problem of estimating the high-order aberrations from the observed starbursts.
