3D Testing
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.

Overview of ARAMIS Sensor Concepts
ARAMIS for Testing Applications
Integration into the testing environment
The associated ARAMIS Controller can be used for easy programming of user-defined measuring sequences, offers image-synchronous signal recording of external measurement signals (e.g., force), transmits analog and digital measurement values and provides numerous options for integrating the system into the testing environment.
Multisensor
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 ZEISS 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.

Power & Energy
The energy sector is facing a huge transformation in the course of the expansion of renewable energies. Energy-producing companies must always keep the safety of their plants in mind. In order to ensure safety, a large number of mechanical tests such as tensile, compressive and bending tests are carried out. In addition, vibration tests on components such as generators and turbines play an important role in ensuring that the components can withstand the high loads caused by vibrations during operation. ZEISS ARAMIS is the optical measurement solution for the determination of strains, deformations and displacements in 3D.
Fields of application
Materials characterization
Precise, full-field ARAMIS measuring results improve the accuracy of material characteristics. Existing evaluation procedures are optimized and become more reliable, such as the determination of flow curves and forming limit curves. Some material tests can only be performed due to the non-contact method of ARAMIS measurements and the high local resolution of the results. This is applied to tensile, shear, compression and 3-point bending tests as well as to high-speed and temperature tests.
Prototype testing
ARAMIS is used for strength and vibration analyses, fatigue limit and crash tests. The measuring results form the basis for determining product durability and load limits and for optimizing the geometrical layout. During load testing, the system measures the real part geometry along with the non-linear deformation behavior and allows for direct comparison with FEM data.
Validating numerical simulations
ARAMIS sensors provide information on material properties, the deformation behavior of parts and the boundary conditions of test setups. The measurement data are used as input parameters for simulation computations and for optimization and validation of FEA models. The software allows for importing FE data from ABAQUS, PAMSTAMP, LS-DYNA and ANSYS, AUTOFORM as well as for aligning them in 3D to the measuring data and in space.
