Abstract
A method for determining a local refractive power in a volume element of a transparent object using a pattern includes observing the pattern through the transparent object by a first camera, determining, using the observed pattern, a three-dimensional (3-D) shape and position of a surface of a particular volume element of the transparent object facing the pattern and using the determined 3-D shape and surface position of the particular volume element, determining a local refractive power for the particular volume element.
