AFIT employs Polytec vibrometer
Staff -- Test & Measurement World, 10/1/2004
The Air Force Institute of Technology (AFIT; Wright Patterson AFB, OH) will employ Polytec's PSV-400-3D scanning vibrometer for experimental modal analysis. AFIT will use the tool, which permits engineers to perform complete 3-D vector component analysis, to measure vibration characteristics of unmanned aerial vehicles (UAV) and other intricate aerospace and vehicular structures.
The vibrometer performs simultaneous measurements using three independent sensor heads and offers noncontact vibration mapping at high spatial resolution. By auto-positioning laser light, the vibrometer decreases setup time and simplifies data acquisition while increasing sample density and total sampled points to more than 250,000. It uses the Doppler (frequency) shift of back-scattered laser light to determine the instantaneous velocity and displacement of a point on a vibrating structure. www.polytec.com.
