Vertical Interferometers
from Polytec, Inc.
Polytec Laser Doppler Vibrometers are precision tools for non-contact vibration measurement. Designed to be quick, easy to operate and free from cross-talk or feedback problems, these instruments determine a structure's velocity and displacement from the Doppler shift of back-scattered laser light.
