In this work, the design and optimization of optomechanical components of a three-mirror anastigmat (TMA) telescope are carried out. The telescope is part of the Rugged Imaging Infrared Spectrometer (RIIFS), a miniaturized Fourier Transform Spectrometer (FTS) developed for future planetary missions. Finite element analyses are used to assess the performance of the design. Besides conventional methods, Generative Design (GD) is used to obtain a variety of design solutions to be realized with Additive Manufacturing (AM), providing good mechanical performance under static and dynamic loading. The proposed solutions are then evaluated according to their mass, stiffness, and dynamic behavior in order to find the optimal design that best fulfills the strict design requirements.

Abstract
In this work, the design and optimization of optomechanical components of a three-mirror anastigmat (TMA) telescope are carried out. The telescope is part of the Rugged Imaging Infrared Spectrometer (RIIFS), a miniaturized Fourier Transform Spectrometer (FTS) developed for future planetary missions. Finite element analyses are used to assess the performance of the design. Besides conventional methods, Generative Design (GD) is used to obtain a variety of design solutions to be realized with Additive Manufacturing (AM), providing good mechanical performance under static and dynamic loading. The proposed solutions are then evaluated according to their mass, stiffness, and dynamic behavior in order to find the optimal design that best fulfills the strict design requirements.Pubblicazioni consigliate
