Turn any single point LDV into a complete scanning laser vibrometer! OMS is the exclusive distributor in the United States for the VibroLaser ScanSet. The ScanSet is an innovative and cost-effective solution to convert any single point LDV into a complete scanning laser Doppler vibrometer system.

Laser Doppler vibrometry is currently the method that offers the best displacement and velocity resolution and is used in many fields of basic science. It enables femtometer amplitude resolution and is linear and therefore has a consistent amplitude right up to the very high frequency ranges – practically reaching more than 2 GHz at present. OMS Laser Scan LS01 - The LaserScan LS01 is a compact yet powerful scanning laser Doppler vibrometer (SLDV). The LaserScan LS01 includes everything required for a complete full-field measurement - the laser vibrometer, scanning mirrors, camera, data acquisition unit, signal generator, laptop computer, and software. We have developed on a new approach to characterize the performance of a laser Doppler vibrometer (LDV). The method uses two acousto-optic modulators (AOMs) to frequency shift the light from an LDV by a known quantity to create a synthetic velocity shift that is traceable to a frequency reference Laser Doppler Vibrometer’s non-contact technique and high frequency capability makes it ideal for Non-Destructive Testing (NDT), Non-Destructive Evaluation (NDE) and Non-Contact Stress & Strain investigations especially those targeting the identification of damage, delamination and cracks in material samples. Laser Doppler Vibrometer is the most common type of laser vibrometer being used these days to measure substrate-borne vibration.
