This thesis, conducted in collaboration with Sodern–ArianeGroup, addresses the modernization of a spectral characterization bench dedicated to the qualification of space-grade optical filters—a key instrument ensuring spectral accuracy and stability in aerospace applications. The legacy motion control subsystem, based on proprietary hardware and undocumented software, had become a critical bottleneck in terms of maintainability, precision, and scalability. To overcome these limitations, a modular industrial motion control architecture was designed and validated, centered on a Zaber X-MCC controller. The work followed a complete engineering workflow, including system analysis, design and wiring of a two-axis prototype, hardware–software co-integration, and the development of modular control interfaces using LabWindows/CVI.
