Measure deformations in real time
The ARAMIS product portfolio comprises sensors for dynamic measurements of 3D coordinates, 3D displacements and 3D surface strain. Based on triangulation, the systems provide precise 3D coordinates for full-field and point-based measurements.
Optical 3D Motion and Strain Analysis
Ideally suited for product development, materials research and component testing
The analyses provide information on material characteristics and the behavior of components under load. These results form the basis for product durability, geometrical layout, reliable numerical simulations and their validation.
Fast and easy test procedure
ARAMIS sensors measure statically or dynamically loaded specimens and parts by using a contact-free and material-independent method based on the principle of digital image correlation (DIC) – without time-consuming and expensive preparations of the test object.
High-precision measurements of small and large objects
The system offers stable solutions for the analysis of specimens of just a few millimeters up to structural components of several meters. The measuring resolution reaches down to the submicrometer range independent of the geometry and temperature of the specimen.
Determination of load limits
The British motor sport company Williams Racing uses ARAMIS SRX sensors in the development of prototypes. Optical measurement technology is used to determine the load limits of parts, select suitable materials and optimize the performance of the cars.

Analysis of physical effect chains
At the Vehicle Testing Centre (FVZ) of the TU Dresden ARAMIS SRX sensors are used to carry out dynamic analyses on complete vehicles in the test bench. Emphasis is given to evaluating the interaction of the parts chassis, axles and tires.

ARAMIS for Testing Applications
Integration into the testing environment
The integrated GOM Testing Controller controls not only the stage acquisition but also the light management. Furthermore, a software-based programming interface is integrated for preset or user-defined measuring sequences.
Combining several ARAMIS sensors allows for measurements from various perspectives with different measuring areas. The measurements are captured and evaluated in one common coordinate system at the same time.
Large measuring volume
Also for dynamic measuring of complex or large applications, ARAMIS makes it possible to evaluate, for example, the vibration behavior of individual blades of wind power plants under heavy load.
Long-term online measurement
Online component testing is used, for example, in durability tests, fatigue tests as well as in wind tunnel tests and vibration analyses. The measuring results can be viewed online or processed live by other programs.
ARAMIS Kiosk Interface – automated check
ARAMIS Kiosk Interface is a user interface for automated evaluation of tensile tests complying with different standards. With minimized user interaction, standardized testing procedures can be carried out fast, easily and repeatable for measurement series with numerous specimens.
Verification of numerical simulation
ARAMIS sensors provide information on material properties of parts. This data is used as input parameters for simulation computations and as reference size for optimization and verification. The GOM software allows importing FE data from formats including ABAQUS, LS-DYNA and ANSYS as well as aligning them to the measuring data and in space.

GOM Acceptance Test
Evidence of the quality and performance capability of most ARAMIS sensors is provided by the GOM Acceptance Test (GAT). The acceptance procedure is based on VDI standards 2634-1 and 2626 and is an integral part of the outbound delivery process. Customers receive a GAT certificate for the purchased sensor, a DAkkS certificate for the optical scale used and a detailed process description.
