Non-Contact Vibration, Velocity, Length and Surface Metrology Measurement Polytec has provided high-technology, optical measurement solutions to researchers and engineers for over 30 years.  Their innovations answer many pressing manufacturing and engineering challenges such as how to improve the noise and ride characteristics of automobiles, enhance the reliability and performance of jet engine structures, study the dynamics of microstructures (MEMS), increase the resolution, precision and longevity of medical surgery and ultrasonic imaging devices or improve the accuracy of the cut-to-length process in a steel mill.    Optical metrology systems offer the ability to characterize a wide range of surface parameters including roughness, waviness and flatness. Quality and Innovation Polytec's market-leading position is built on innovative technology, high-quality products, engineering excellence, highly qualified and customer-oriented service, expert technical advice and thousands of satisfied customers worldwide. By continuously developing new trendsetting metrology, Polytec is your best choice for today and tomorrow. From Single Point Monitoring to Complete Modal Analysis Polytec develops hardware and software for complete non-contact vibration measurement and analysis. From single-point to completely scanned areas; from out-of-plane to in-plane to complete 3-D motion vectors; from near-DC to 600 MHz; from picometer-level motions to the high dynamics of explosive events and from nanostructures through microscope optics to buildings at long range: Polytec has measurement systems that suit even the most demanding applications. Uncompromising Accuracy and Large Bandwidth Polytec's vibrometers use heterodyne detection to precisely measure the Doppler or phase shift of back-scattered laser light. Velocity and displacement signals can then be provided by a choice of decoder determined by your measurement requirements. User Friendly Polytec technology builds on the premise that non-contact vibration and velocity measurement is fundamentally non-destructive, easily aligned, and minimizes the need for time-consuming accelerometer mounting, wiring, and signal conditioning. Hardware is designed with the user in mind, providing instruments that are simple to operate and sensors that are easily integrated into the CAE design and test process. Intuitive software permits the user to quickly and confidently begin collecting data and then export data for various tasks including modal analysis and validation of finite element models. Global Support and Services Polytec is a global corporation with facilities in Asia, North America and Europe and representatives all over the world. So if you are interested in characterizing vibration and velocity of structures ranging in size from MEMS to a 747, through either an investment in their equipment or measurement services, contact Polytec for experienced and innovative solutions built upon experience.
