Polytec Laser Velocimeters

---

Polytec is the world leader in Laser Doppler Vibration Measurement and Laser Speed Measurement. 

Polytec Laser Surface Velocimeters (LSV) measure speed and length of moving surfaces accurately and without contact.  LSV' measure accurately on coils, strips, tubes, fiber, film, paper, foil, composite lumber, and almost any other moving materials, including hot steel. Polytec Laser Scanning Velocimeters perform continuously in harsh environments and are easily interfaced trhough digital or analog interfaces.

Operating Principle The sensor head incorporates a frequency stabilized laser diode (German patent), highly sensitive APD (Avalanche Photo Diode) detector and an optical frequency shifter (Bragg cell)  Click here for more information on Laser Scanning Velocimeter Operating Principle

Polytec's LSV systems are designed to perform continuously in harsh environments. The LSV control processor is easily interfaced to your process by its digital or analog interfaces. Don't take chances.  Call us and benefit from Polytec's long experience in laser-based speed/length measurements.
