WebA laser surface velocimeter ( LSV) is a non-contact optical speed sensor measuring velocity and length on moving surfaces. Laser surface velocimeters use the laser Doppler principle to evaluate the laser light scattered back from a moving object. They are widely used for process and quality control in industrial production processes. WebOur product range includes coordinate measuring machines, optical and multisensor systems as well as metrology software for the automotive, aircraft, mechanical …
