Abstract
This article presents the design of a capacitive sensor that can detect piston errors as well as lateral displacements between two adjacent MI segments. Due to the measurements' statistical analysis the resolution acquired will be nanometric. This precision is required to achieve the image quality expected for the whole primary segmented-mirror.
