The aim of the present work is a study on the optical characteristics of one
arm of the LISA interferometer, coupled with the need of characterizing the
far field wavefront. The goal is to identify if it is possible to configure two
telescopes with some construction aberrations in a position which ensures
good performances. This is done by changing the optical characteristics of
the telescopes in a Montecarlo Simulation.
In the first chapter a brief overview on the LISA mission is presented: it
is explained the goal of the mission and the main structure of the all three
satellites.
In the Chapter 2 the model used in the project is described. It represents
only one arm of the triangular interferometer, in which both telescopes are
considered as sender and receiver. In the same chapter, the mathematical
assumptions considered during the realization and the metrology chain used
in the model are explained.
Chapters 3-4-5 are dedicated to the explanation of the algorithm invented
to configure the two telescopes during the calibration procedure: first of all
an introduction on the goal, the requirements and the conditions applied
in the algorithm, then the description of the strategy adopted and in the
Chapter 5 the results obtained with the Montecarlo Simulation.
Chapter 6 is centered on an alternative approach to the same problem.
This different idea for finding the best configuration of the two telescopes
explored in this chapter is now only in a beginning phase but already gives
some good results, them also explained in the text.
The work concludes with an overview on the entire project and results
and with some suggestions for future developments.
