Description succincte (Anglais)	Compact 1D optical encoders for angular positioning measurement systems
Résumé des résultats (Abstract) (Anglais)	This project addresses the development and the realization of future optical systems for angular posi-tion measurements. Angular encoders are core modules in Leica GeoSystems surveying instruments. Next generation instruments need significant smaller modules and faster read-out speed. Conse-quently the writing density of the code pattern must be increased without loosing the high angular accuracy (1').We aim to develop a novel optical system for the position reading sensor: - to improve the image formation and to overcome diffraction problems - to increase the signal-to-noise ratio for higher data rate The outcome is a bench top prototype with improved compactness and cost saving potential.
