Vibration Analysis with WaveCam Optical Flow Based Time and Frequency ODS Our video vibration analysis solution WaveCam is the perfect tool for non-contact and high-resolution vibration measurement for experts and beginners in the time and frequency domain. To get started, all you need is a camera and our software to process the data. Save the time to set up individual sensors, or measurement locations. A frequency ODS can be performed with a single excitation in a wide range frequency range. The dispensation of consecutive excitation for different measurement positions saves measurement and test bench time respectively. Highspeed camera Chronos 2.1 with WaveCam software by gfai tech WaveCam makes vibrations visible with motion magnification Analyze data in the time, frequency and order domain Compatibility with various video formats, regardless of the camera used Measurement resolution of 10-4 pixel possible with use of artificial intelligence (AI) Measurement from small (e. g. circuit board) to large structures (e. g. buildings) Cross-validation with finite element analyses and traditional vibration measurement methods Depending on the frame rate of your camera, a minimum frame rate FPS = 2 x fmax is required to capture the highest frequency of interest fmax. For maximum flexibility we recommend employing a Chronos highspeed camera exceeding 1000 fps. Vibration displacements of minimum 100 nm are captured. Every single pixel serves as an individual sensor allowing you to measure hundreds of thousands of positions simultaneously. Time waveforms and frequency data can be extracted for individual positions. Results were cross-validated with conventional methods namely laser Doppler vibrometer (LDV), accelerometer as well as acoustic holography. Display deflection shapes of structures during operation, manual, ambient or automated excitation e.g. using the impulse hammer WaveHitMAX as well as transient events. Various options to display the data, facilitate interpretation and export vivid and conclusive results.
