SMART 3D-Fiber: Next-level precision in vibration measurement

The 3D-Fiber is a perfect example for 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 directions of space. This is achieved by combining data of three interferometers in the same compact device with highest precision, revolutionizing how vibrations can be analyzed with laser Doppler vibrometers.

By simply replacing the 3D-Fiber head with up to four heads separate to the body, the 3D-Fiber is able to capture the vibration data on four different channels simultaneously. This flexibility enables engineers, researchers and students alike to gain insights in the vibrational behavior both in and out-of-plane as never before.

With its unique combination of features, the 3D-Fiber truly is a lab in a device, combining highly-precise 3D vibration measurements with multi-channel data acquisition and an arbitrary signal generator. Seamless synchronization with other SMART series devices makes the SMART 3D-Fiber the ideal choice for research and development of complex products.
