A scanning laser Doppler vibrometer (SLDV) is an extremely precise noncontact vibration measurement device used across the automotive, aerospace, and naval industries. SLDVs can measure at a near-limitless number of scan points along a structure’s surface to obtain the vibrational response. These devices offer flexibility in the kinds of test you can run as well as greater control of how and where the laser will scan across the structure, promoting faster workflows and more automated data collection procedures to help you assess the quality of your products.
In this webinar, ATA Engineering presents an overview of what an SLDV system is, how it obtains data from the infrared laser, and the various applications of a laser vibrometer for testing. ATA also analyzes data collected with a laser vibrometer in the context of operational modal analysis in a vibration control test, animating the operational deflection shapes of the structure, extracting the modal parameters inside Testlab, and assessing the reliability of the results with some new features of Testlab Neo.
