SMART 3D-Fiber

New Dimensions in Vibration Analysis 

Combine the advantages of our flexible fiber system with highly precise 3D vibration data.

The 3D-Fiber from the SMART series allows precise, non-contact vibration measurements in three dimensions using a single device that integrates multiple functionalities. This device can handle up to four separate measurement channels simultaneously, offering flexibility and advanced data acquisition capabilities. Its compact design and compatibility with other SMART series devices make it ideal for complex research and product development tasks.

3D Head: Explore three-dimensional measurements

Our 3D head is designed to provide a comprehensive view of your subject. Three laser beams emerge from one head at different angles, allowing you to capture the object's movement in all three spatial directions. This feature is particularly valuable for applications such as detecting deformations.

Modular and extendable fiber system

The modular and extendable Multi-Fiber system is designed for adaptability and scalability. This allows you to customize the setup to meet your specific measurement needs, ensuring both precision and versatility.

 

Synchronized measurements

Experience the accuracy of perfectly synchronized measurements. Our system ensures that data collected from multiple points is precisely aligned in time, offering a coherent and detailed analysis of vibrational phenomena.

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.
