For Scanning Vibrometers

The data-acquisition software for scanning vibrometers presents the measurement results in an intuitive, graphically animated format. An interface enables the export of the measurement data into external software or the import of 3D geometry or FEM data.

Together with the Optomet scanning vibrometers, the OptoSCAN software is the intuitive solution for non-contact vibration measurement, visualization and analysis.
You can use it to quickly and easily determine transfer functions, natural frequencies, operating deflection shapes (ODS) and eigenmodes.

Measurement data in the time and frequency domain is clearly represented as graphs, and modes are visualized by 3D animations.
Interfaces to external software permit easy data exchange e.g. with FEM applications, with MATLAB® or Siemens LMS TestLab®.


Laser-scanning measurements with OptoSCAN - Easy, Intuitive, Fast!

OptoSCAN is designed to help you get the most out of the outstanding performance of your Laser Scanning Vibrometer. The software was developed on the basis of C++ in the 64-bit structure and has a full multicore support. The result is an extraordinarily fast program flow, which enables a live analysis of the measurement data during the measurement process. Furthermore, the continuous development of the software ensures a steadily increasing number of features, which are tailored to the needs of the customers. Thus, the interplay between OptoMET's world-leading laser vibrometers and the OptoSCAN software ensures the fastest track to precise vibration measurement data.

The typical procedure of a laser-scanning measurement

Dealing with OptoSCAN is very easy. Five tabs on the left edge of the interface - Files, Device, Geometry, Acquisition and Analysis - guide the user through the measurement project in a logical and intuitive sequence.

Files - Loading/saving project data and the UFF-export

The first tab is for loading and saving your projects. A tabular overview of the last measurement projects is shown on the right side of the program surface. Each file is displayed with a matching automatically generated screenshots of the measurement object, which in turn simplifies the correct identification of the stored project files.

Device ­­­- Measuring ranges, filters, and vibrometer settings

In addition to fundamental settings for the scan measurement, hardware settings of the vibrometer can be remotely controlled in this window. Various filters, the optical focusing of the laser, and the measuring ranges of the measured vibration quantities - distance, speed, acceleration - can be controlled from here. The same settings can be found on the LCD display of the vibrometer itself.

Geometry - Create the measurement mesh

The third tab defines the distribution of the measuring points. First, the object to be measured is framed with a rectangular, circular, or any other shape. The shape, size and geometry can be arbitrarily manipulated as in a technical drawing program.
Next, a measurement grid is defined within the frame. Rectangular, circular, or triangular grids are available. By manually creating measuring points and grids, individual measuring meshs can be created.

Acquisition - Data acquisition settings

In Acquisition the data acquisition is started. In the central window is a video stream of the object with measuring points. Points are selected like icons in Windows. The left-hand area controls the measured frequency bandwidth, the spectral density, and further measurement-specific settings. The internal signal generator is controlled in this tab, too. A preselection of commonly used functions such as sine, chirp, noise, etc. and an import of arbitrary functions are available. Below the stream, graphs show the time data and frequency functions of the measured points.

Analysis - Frequency and time representation of the measured data

The last tab of OptoSCAN contains the analyzed data of the measurement. Below the central window, graphs show the time data and various frequency functions, e.g. the Frequency-Response-Function (FRF), of the measurement points.
The central window shows the animation of the measured vibration data over the entire surface. Switching between time and frequency representation is possible at any time. Certain times or frequencies can be selected in the graphs.

The described steps are only a brief description of the actual functionality of OptoSCAN and the Laser Scanning Vibrometer. Specific details regarding the functions of the Vibrometer and OptoSCAN are listed in the data sheet of the Laser Scanning Vibrometer.
