Abstract
[fr] The aim of this master thesis is to perform an optimization of the Narrow Field of view Imager (NFI)
of the GLIDE mission (NASA) and to study its tolerancing. The optimization process is developed
around a geometrical problematic that appears between the first mirror of the telescope, the detector
and the light path. Indeed, the first design of the NFI created during phase A of the mission showed
that there was a collision between those components. The main goal is to solve this problematic and to
develop an optimization process to have the most optimal optical system. The design created will have
to respect the requirements of the mission. The second goal is to study the tolerancing of this system.
A sensitivity matrix is built in order to see which geometrical parameter are the most sensitive in the
optical system. This will also allow to define a tolerance for each dimensions of the NFI telescope.
