Mirror Support

The Mirror is supported through one hole in the back where a dowel is inserted.The Mirror is falling: the dowel is touching the mirror not in the barycenterActuating ribbon works against g and givesvertical axis alignmentA second actuating ribbon at 90 deg givesthe horizontal axis alignmentPiezo motors are used to pull the ribbons

System heavily tested in Lab in Firenze
