Using the same technology that robotic vision and autonomous vehicle companies utilize to detect objects in motion, MEscope Video ODS™ accurately measures surface vibration from a high-speed video recording. Using accurate time waveforms or frequency spectra extracted from the video, all of the time-tested features of MEscope can be used to document the vibration.

With the MEscope Video ODS™ package, you can post-process the time waveforms or frequency spectra extracted from a vibration video recording, and record clear color videos of the ODS animation.  You can also store the time waveforms. frequency spectra, ODS’s & videos in a machine-based archival database.

Video ODSTM Use Example

A new Breast Roll “Shaker” was installed on the wet end of a paper machine to create better alignment of the sheet fibers. An unintended consequence of this new component was it created a potential resonance excitation source of vibration.  

Using an Iphone 10 cell phone set on Slow Motion (240FPS), a set of Video ODS data was taken while the shaker was running to define the transmission of energy through the structure.   The shaker was found to be exciting the forming section wire roll return. The elevated vibration was found to be loosening bolt connections in the roll support structures.
