Overview
The laser beam of the Scanning Laser Vibrometer is positioned by two PC controlled mirrors. The built-in HD camera captures the live display of the test object. On this image the measurement points can be easily arranged with the integrated drawing tools. The defined points are scanned automatically by the ScanSet software.
The ScanSet provides all components of a Scanning Laser Vibrometer.
Simply fix the Laser Vibrometer with the quick release clamps to the ScanSet adapter, adjust the mirror unit by the linear slides and you are ready for the scanning measurements.
The ScanSet is shipped with a Data Acquisition with analogue input channels to measure the laser- and reference signals. The user-friendly measurement and analysis software quickly processes the vibrations data, graphical displays, images and animations of vibration shapes in frequency and time domain.

ScanSet
The ScanSet holder is manufactured from aluminium to carry the Laser Vibrometer and the Scan head with camera and mirrors. To ensure that the laser beam of usual Laser Vibrometers hit the mirrors in centre position, the ScanSet offers linear slides that can be fixed by clamping lever to ensure a precise and reliable position. Using a ScanSet for measuring the signal quality is only dependant on the specifications and quality of the used Laser Vibrometer. The Scan head is connected to the controller by a single cable available in different length.
Controller
The controller includes the power supplies, the mirror controller and the data acquisition system. Signal can be provided by BNC connectors for the input channels and the generator output. Communication to the PC is established by a single USB connection
