In combination with the Optomet scanning laser Doppler vibrometers, the OptoSCAN software forms a complete solution for imaging vibration measurements.
OptoSCAN combines point by point scanning data with geometry information to animate vibrations and surface waves of nearly any test object for design optimization, solving structural problems, validating FE Models and fundamental research. Data is displayed in numerous time and frequency based quantities.
OptoSCAN was developed as a tool for the simple and efficient use of the Optomet scanning laser Doppler vibrometer. The modern 64-bit multithreaded software ensures smooth operation even with large amounts of data. A live analysis of the measurement data during the measurement process is also possible. The software can be used with standard PC hardware running Windows 10, therefore data acquisition, analysis and visualization can be easily handled on almost any PC.
OptoSCAN remote controls all the hardware settings and components of the scanning vibrometer. The video camera and measurement laser are calibrated, decoders and measurement ranges are defined, channels for measuring and reference signals are defined, and the built-in signal generator is controlled.
Grids for the measurement points can be created and edited with just a few mouse clicks. Even complex geometries can be created easily and intuitively. After defining the measurement duration, bandwidth, frequency resolution and settings for quality requirements for the point-by-point measurements, the measurement scan can be started. Colour coding of the grid points shows the scan progress and after the scan provides information regarding the status of each point.
The results are clearly displayed in diagrams, waveforms can be represented as two-dimensional maps or three-dimensional animated time profiles. A simple switch between time and frequency display enables a comprehensive analysis of the measurements. Resonances, transfer functions, vibration modes, operating vibrations or the propagation of waves are clearly visualized.
Real time measurements are displayed during the scan, and the complete analysis is possible immediately after the scan is completed without having to switch to a dedicated analysis mode.
Offline processing is possible with a desktop version of OptoSCAN. With the help of the integrated video creation tool, the results can be quickly and effectively reported or shared.
OptoSCAN projects are clearly stored and can be read in again along with all settings for future analysis. Extensive exporting options are available for further processing of the measurement data outside OptoSCAN. Documented and open file formats enable easy exchange with programs from third-party providers, for example for modal analysis or with standard software such as MATLAB®.
Using OptoSCAN is very easy. The structure of the user interface is based on the typical workflow of a scanning vibrometer measurement: definition of the measurement project, selection of the channels and measurement ranges, definition of the geometry and measurement points, selection of the acquisition parameters and finally presentation and analysis of the measurement results. New users are guided intuitively through the measurement process, and experienced users can enjoy comprehensive functionality.
