SMART 3D-Fiber: Maximum Precision in Vibration Measurement
The SMART 3D-Fiber perfectly demonstrates the versatility of the new SMART series: Using the same hardware as the SMART Multi-Fiber, it enables non-contact vibration measurements in all three spatial directions. It achieves this by combining data from three interferometers in a compact, ultra-precise device, revolutionizing vibration analysis with laser Doppler vibrometers.
By simply replacing the 3D-Fiber Head with up to four heads separated from the housing, the SMART Multi-Fiber can acquire vibration data on four channels simultaneously. This flexibility enables engineers, researchers, and students alike to gain unprecedented insights into both in-plane and out-of-plane vibration behavior.
With its unique combination of features, the SMART 3D-Fiber is an all-in-one laboratory, combining high-precision 3D vibration measurements with multichannel data acquisition and an arbitrary waveform generator. Seamless synchronization with other devices in the SMART series makes the SMART 3D-Fiber the ideal choice for researching and developing complex products.
