Differential Vibrometers
For the measurement of "out-of-plane" differential vibration Polytec offers dual-beam systems. Differential vibrometers allow vibration measurement between two points vibrating relative to each other. Specialized fiber optic probes allow the examination of locations that are difficult to access.
