Ultra-fast precision motor with X, Y and Theta motion and ultra-fast optical decoding and absolute position detector

摘要

A high-speed and extremely large range positioning apparatus capable of producing motions in multiple dimensions with high precision and very high reliability. An ultra fast absolute position sensor providing instantaneous position readings with sub nanometer precision on full range of relative positions. A set of optical encoding schemas providing high encoding density and extremely fast decoding regardless of their planar positions. A flexible reshape-able motor with multiple degrees of motions
