Laser surface velocity measurement 'in more than one dimension' for planetary mills

Here, Polytec Laser Surface Velocimeters (LSV) are used to measure length and velocity in a wide variety of industries - not only in a planetary mill, but also on different planets. Polytec Laser Surface Velocimeters, overcome the challenge in the process control of a planetary mill and others as a result of their extensive interface concept, the process-oriented accessory range and their unique optical configuration. Several rollers (e.g., four) are arranged at an angle around the red-hot rolling product in a planetary mill.
