DIC Standard 3D

Image of Q400 DIC system

The Digital 3D Image Correlation System Q-400 is an optical measuring device for true full-field, non-contact, three-dimensional measurement of shape, displacements and strains on components and structures made from almost any material.

The Q-400 system is used for determination of three-dimensional material properties in tensile, torsion, bending or combined tests. In addition, deformation and strain analysis can be applied to fatigue tests, fracture mechanics, FEA validation, and much more.

A Wide Range of Applications

The Q-400’s flexible design enables a wide range of applications from microscopic investigations on microelectronic or biomedical materials to large scale measurements of aerospace, automotive, marine and railway components.

  • Advanced materials (CFRP, wood, fiber injected PE, metal foam, rubber, …)
  • Component testing (shape, displacements, strains,…)
  • Material testing (Young’s Modulus, Poisson’s Ratio, Elasto-Plastic Behaviour)
  • Fracture mechanics FEA validation
  • High-Speed applications (dynamic measurements, transient events)

Real-time Full-Field Correlation and Export of Data

The Q-400 DIC evaluates data in real-time and enables the user to export data simultaneous as an analog voltage signal.

User Friendly System

Our Istra4D software is designed to be intuitive and easy to use. All measurement parameters can be stored and re-used for repeating or similar measurement series. A speckle quality indicator further supports the evaluation of the correct pattern and optical setup at the beginning of the measurement. Predefined parameters help the user to decide on the correct DIC setup. The system comes with robust packaging for harsh environments.

Easy Calibration

All system parameters are determined by a fast and easy calibration procedure – a very practical and simple process by positioning a calibration plate in front of the cameras. The achieved calibration accuracy is displayed online after the calibration.

Multi Camera System

An easy extension of the Q-400 is from a 2 Camera to a 3 Camera system, increasing the field of measurement, improving the measurement of curved objects and increasing the accuracy. The multi camera system supports any number of cameras from 1 to 8. The system uses a cluster approach combining images without stitching and using a single global axis system. A multi camera system with 8 cameras can cover 360° of a cylinder and 4 cameras can measure both sides of a specimen to accurately determine thinning.
