Scanning Laser | ScanSet
With the Scanning Laser Doppler Vibrometer, the laser beam is positioned using two computer-controlled mirrors. The measurement points are defined interactively on the video image of the measurement object. The vibration measurement is automatically carried out by the computer at the specified points. In comparison to complete systems, the developed ScanSet can be operated with different laser vibrometers. It turns a standard single-point laser vibrometer into a fully-fledged scanning laser vibrometer in just a few simple steps. To do this, the single point laser vibrometer is simply fixed using the quick-action clamping devices and the measurement can start. The ScanSet has its own data acquisition with analog inputs for measuring the laser and reference signals. The user-friendly measurement and analysis software enables evaluation of the vibration data including graphical vibration shape animation in short time.

VibroLaser Scanset Components:
ScanSet
The VibroLaser ScanSet is manufactured from robust aluminium, and has next to the high precision laser deflection unit a CCD-Camera for photo realistic capture of the measurement object. To ensure that the laser beam of any usual Laser-Vibro meter exactly hits the mirror axis in zero position, the VibroLaser ScanSet offers linear slides that can be easily fixed by clamping lever to ensure a precise and reliable laser positioning. Using a ScanSet for measuring the signal quality is only dependant on the specifications and quality of the used Laser Doppler Vibrometer. The electrical connection to the controller is simply realized by a single cable that also supplies the mirrors with power, takes care about the mirror and camera steering and carries the measurement data and CCD-Camera Signals.
ScanSet Controller+Optic
Controller
The controller includes next to the power supplies, an electrical component to steer the mirrors and a data acquisition system to digitize the vibration signals. The controller has a direct connector for the central cable to the ScanSet, BNC connectors for the input channels and the generator output and one USB connector to communicate with measurement PC. The Notebook/PC is only connected with one USB-cable for mirror and CCD-Camera steering, vibration data and video stream.

Module for ODS in time domain
Reproducible transient operations can be measured and saved sequentially with the ScanSet. If the measurement are triggered with a reference channels, the single channel measurements can be combined to a multi-channel-measurement with synchronous time series. This signals can be played back as animated time movie. The transient movement of technical structures can be shown in slow motion. Typical applications are:
Animation of wave propagation in technical structures
Fault detection in composite materials (Delamination)
Presentation of periodic movement of machine parts
The example shows the wave propagation in a brake disc after impact excitation measured with 2500 single point measurements.
