Calculating distortion and three-dimensional displacement! We respond to applications that require material property values.
Images captured with a high-speed camera can be used to calculate three-dimensional coordinates of the surface, displacements and velocities in three-dimensional space, as well as maximum/minimum principal strains and strain rates. It is also possible to compare and evaluate the shape data obtained from CAE with analysis simulations. Since the measurements are conducted non-contact, they can be used even in test environments with high temperatures, shocks, and vibrations. 【Features】 ■ Non-contact strain measurement: Capable of measuring strain on a wide range of materials such as metals, plastics, and fibers. ■ Three-dimensional measurement: Using two high-speed cameras, it captures the positional and shape changes of a randomly applied pattern to measure strain. ■ High-speed sampling: Detailed measurements at up to 1.12 million frames per second. ■ Easy measurement operation: Graphically compares the condition of cracks and strain distribution. *For more details, please refer to the related links or feel free to contact us.
