Drift Reduction of a 4-DOF Measurement System Caused by Unstable Air Refractive Index

Drift Reduction of a 4-DOF Measurement System Caused by Unstable Air Refractive Index

Laser beam drift greatly influences the accuracy of a four degrees of freedom (4-DOF) measurement system during the detection of machine tool errors, especially for long-distance measurement. A novel method was proposed using bellows to serve as a laser beam shield and air pumps to stabilize the ref...
