Stress and deformation measurement

Our new holographic measurement camera can measure full 3D vector fields of surface deformations with extreme sensitivity.

Unique advantages of holographic stress measurements

Greater precision

1.) complete information about the displacement field to calculate the stress

• full field measurement (and at each point simultaneously) everywhere on the surface, at arbitrary distances from the edge of the hole3D vector displacement measurement and with this stress/li> more accurate

General applicability

2.) measurement possibility for curved or distributed surfaces

3.) measurement possibility for surfaces with limited access (near curves or corners)

4.) reduced requirement for surface quality (cleanliness, surface roughness)

Reduced requirements towards the environment (within optical working conditions)

5.) relative temperature independence

Less preparation time

6.) one-step preparation (if the required support surfaces are available)

• only initial fixation in the measurement palette

Better repeatability in "real time"

7.) fast and unlimited repeatability (with hole re-drilling)

• possibility to monitor changes of the stress field on the surfacepossibility to monitor changes of the stress field over time (in spontaneous or intentional changes, too)possibility to monitor the quality of nominally identical objects (in serial production)

Not needed

8.) any kind of consumables (strain gauge, special glue, etc.)

9.) Precise positioning of the perforations

10.) Accurate Electronic Data Collection
