ARAMIS, the deformation measuring system is used for recording an object under load using CCD cameras. For each & every stage of load, this system calculates 3D coordinates of the object surface on the basis of digital image processing delivering the 3D displacement and the strain. ARAMIS sourced from GOM, Germany is a non-contact measuring system ideal for measuring 3 dimensional deformation and strain distributions of real components under static or dynamic load.
The ARAMIS systems finds applications:
• Material testing
• Characterization of creep and aging processes
• Component dimensioning
• Examination of non-linear behavior
• Strength assessment
• Determination of Forming Limit Curves (FLC)
The different salient features of ARAMIS include:
• Large measuring area from small to large objects (1 mm up to 1000 mm)
• Simple preparation of the specimen because ARAMIS works on both, random and regular patterns.
• High data point density
• Highly efficient and flexible system due to a compact measurement set-up and highly developed analysis software.
• Strain can be measured in the range of 0.05% up to several 100%.
• Good understanding of the component behaviour by the use of graphical representation of the measuring results.

Avail from us, ARGUS – the system for deformation measuring of sheet metal in the stamping process. During the stamping process, an electrochemically etched pattern deforms with the part and is optically recorded after wards. The 3 dimensional coordinates of the pattern are calculated and then are used to define the shape of the deformed part. The other functions of ARGUS system include strain distribution, thickness reduction and limit diagrams formation that can be calculated. The measurement is graphically displayed through clear display that helps in easy verification of the shaping process. The different areas having huge deformations are highlighted as 'hot spots'.
ARGUS from GOM, Germany is ideal measuring system finds application in:
• Detection of areas with critical deformation
• Solving complex forming problems
• Optimization of stamping processes
• Verification of stamping tools
• Verification and optimization of numerical calculations
The different features of ARGUS, the measuring system are:
• High accuracy and high data point density.
• Compact design, hence easy transportation of the system
• Flexible measuring area allows unrestricted measurement of small sub-areas up to large and complex parts.
• A calibration of the system or an adjustment to the optical properties of the specimen is not required.
• High level of consistency of the measuring values due to automatic calculation routines.
• An interactive intervention in the processing is possible but not necessary.
• Fully automatic identification and the determination of the points as well as the calculation of the strains on the specimen.
• The evaluation speed and the convenient graphical user interface provide excellent productivity enhancement in sheet metal forming processes.

The ESPI, interferometric method is used for measuring smallest 3 D-displacement and plane strain with a resolution of approx. 10 nano meters or 1 micrometer per meter. The tested object is illuminated by the ESPI sensor heading with laser light and is recorded by a CCD camera. The interference pattern caused by the laser and observed by the CCD camera includes the information of the deformation in each visible point of the measured object with a resolution of 10 nm or 1 µm/m. this equipment helps in better product development process that encompasses the component optimization, usage of new materials and the improvement of FE calculation models.
Developed by GOM, Germany, we source and supply the interferometric method ESPI that is ideal for varied applications like:
• Optimizing constructions
• Characterizing heterogenous materials
• Quality control of honeycomb and sandwich structures
• Determining the linear behavior, even of brittle materials
• Characterizing the transition range of two different materials
The varied salient features of ESPI are:
• Simple operation: The compact sensor head mounted on a robust test arrangement along with the user-friendly software allows a quick training and efficient measurements.
• Flexibility: The same sensor measures small and large objects (10mm up to 600mm).
• Non-contact measurement: The ESPI systems measure without contact, therefore no force and no sensor mass is applied.
• Full field and graphic results: The results comprise a large number of data points. The high data point density and the graphic display of the results are leading to a better understanding of the component under load.
• Mobility: Compact construction helps in ideal for measuring workpieces and components on-site.

For better product development, PONTOS is required for a good understanding of dynamical component behavior for simulation verification, vibration analysis or measurement of relative movement. This system helps in delivering the dynamic, accurate and synchronized position of an unlimited number of markers.
The other usage includes:
• Determination of displacement of the markers, graphically visualized or exported by capturing images at different load or movement situations.
• Defining and evaluation of rigid body movement, object deformation or dynamic behavior of the object under load
Functioning on the basis of GOM's two camera technology, the image acquisition uses flexible triggering techniques and is linked to the load situation, including recording of analog signals. The rugged construction, compact design and transportable set up help in precise positioning, movement and deformation values for industrial applications.
The areas of usage of our PONTOS include
• Verification of conceptual design studies and numerical simulations
• 3D measurement of movements, deformations and vibrations
• Measurement of the dynamic behavior, rise and fall of structural vibrations up to 250 Hz (full frame, Nyquist criteria)
• Load, creep and aging tests including complex structures and visco-elastic elements
• Analysis of motion sequences
• Noise, Vibration and Harshness (NVH) measurements in automotive including wind tunnel environments
• Alternative to measurements with accelerometers up to 250 Hz (at full image sizes)
• Measurement of relative motion
• Simple measurement of dynamic gap and flush
The different salient features of our PONTOS include:
• Non-contact and accurate measurement of the 3D positions of an unlimited number of markers
• Frame rates of up to 480Hz, independent of the number of the captured markers
• Mobility and flexibility due to the light weight and compact design
• Insensitivity to ambient condition changes, such as vibrations and light changes
• Easy adjustment to different measuring areas and tasks
• Measurement, visualization and export of the exact 3D position and movement of the measuring markers in multiple stages
• Customized triggering of the image acquisition based on the load situations (including the recording of analog signals)
