Imagine you just need a camera and software to visualize the vibration of complex structures! No expensive hardware, no cabling and complex post-processing but results within minutes – independently of size and complexity of your structure. WaveCam opens this possibility for you with Optical Flow tracking it gives you motion magnification and modal analysis based only on video data. Analyze your vibration data in the time and frequency domains to gain deeper insights into the dynamics of machines, buildings, and structures.
All you need to get started is a camera and our software to process the data. Save valuable time by eliminating cables and conventional sensors, or by avoiding the need to measure each position individually. Each pixel acts as a sensor, enabling comprehensive motion tracking and vibration analysis across the entire surface.
WaveCam allows you to evaluate hundreds of thousands of positions simultaneously. Time waveforms, frequency data, operational deflection shapes and modes can be extracted from the video. Measurements can be projected into possible desired perspective, enabling intuitive interpretation from various viewpoints. Results have been validated with finite element analysis and traditional sensors such as laser Doppler vibrometers (LDV), accelerometers, and acoustic holography.
You can visualize deflection and mode shapes under operational, ambient, manual, or automated excitation (e.g., impulse hammer WaveHitMAX), as well as transient events.

WaveCam - Video Vibration Analysis on a Car Engine
In this video, you can see our vibration analysis software WaveCam in action during a vibration measurement on an engine.
With the help of high-resolution video recordings and motion amplification, WaveCam visualises even the smallest vibrations in complex assemblies such as car engines. The software supports engineers in analysing the NVH (noise, vibration, harshness) behaviour of drivetrains in detail - both on the test bench and directly in the installed state. In this way, optimisation potential for combustion engines and electric motors can be identified at an early stage of development in order to ensure the highest standards of quality, safety and comfort.

Vibration Analysis on Bridge Model
By studying a bridge model's dynamic behavior under different forces like traffic loads and wind gusts, we gain crucial insights into its structural integrity and resilience.
Using our advanced simulation software WaveCam, even the tiniest fluctuations in the bridge's response can be detected.
This innovative approach not only allows for a more thorough understanding of a bridge's natural frequencies and mode shapes but also facilitates early detection of structural anomalies or damage.
