Laser-interferometric Length Measurement Tracking System


Introduction

This study deals with a two-degree-of-freedom special manipulator for tilting a set of a laser light source and a detector around two axes. Six sets of this manipulator is planned for feedback sensors to measure six-degree-of-freedom relative motions between a tool spindle and surface plate of a precision machine tool or a coordinate measuring machine. Each laser tracker consists of a laser-interferometric length measurement sensor and a 2-degree-of-freedom parallel kinematic manipulator driven by two VCM linear actuators.
