Use of free-form surface to simulate local refractive index changes in plastic lenses measured using polariscopic device

In this paper we propose a method to convert the local variations of refractive index into local changes of one surface of the lens, which then can then be described as a free-form surface, easy to introduce in conventional simulation tools. The proposed method tries to provide an equivalent model o...
