Exploring optical aberrations with two experimental techniques. Applications on Ophthalmic Optics
This work focuses on the general description of two methods for wavefront analysis: wavefront measurement by means of Shack-Hartmann (SH) wavefront sensor and Point-Diffraction Interferometry (PDI); and its potential applications.

| Sumario: | This work focuses on the general description of two methods for wavefront analysis: wavefront measurement by means of Shack-Hartmann (SH) wavefront sensor and Point-Diffraction Interferometry (PDI); and its potential applications. The basis of each technique is broadly described and a dual experimental set-up configuration is presented and its corresponding results are shown. A general overview and description of geometrical aberrations is carried out, in order to present the mathematical framework that these techniques are based on. The main goal of this work is to experimentally demonstrate the equivalence of this both techniques within the experimental error (i.e. to point out the limit of the equivalence between results obtained with both techniques), and to show if it is possible to design a complete dual set-up which uses both techniques for wavefront characterization. Finally, application of those techniques in the field of Ophthalmic Optics is pointed out through the proposal of different set-ups. |
