"The main objetive of this thesis is to present four new methods for optical interferometry images developed during the Ph.D. Three of these new methods were published in international journals (chapters 2 trough 4); the other method (listed in chapter 5), is in the process of publishing. In order to understand the new methods shown in this thesis we will present the theorical principles of optical metrology as well as already published methods, same which would serve as basis for the new developed method presented here. The purpose to develop these methods was to solve common problems in interferometric images."
