StrainMaster |iDIC Micro-Scale Measurement of 3D Strain, Displacement and Shape

StrainMaster µDIC Technology for Small Scale, Full Field Strain Measurement StrainMaster from LaVision combines the most advanced Digital Image Correlation (DIC) algorithms with the highest quality hardware to provide a complete system for materials analysis. StrainMaster µDIC systems use advanced imaging optics and illumination to unlock measurement capabilities at the micro scale. StrainMaster µDIC can be supplied as a complete turn-key system or as stand alone software for importing and processing images from an external source such as a Scanning Electron Microscope (SEM). As a complete system...

StrainMaster µDIC Low Cost System Configuration Where a test is to be conducted to look at strain development on a flat surface, often a one camera 2D system will be capable of producing the data required. The main advantage of these configurations is their simplicity and low cost. LaVision has a selection of cameras with small pixels which are well matched for micro-DIC applications. High pixel density and small chip configurations mean simple macro lenses with a 1:1 magnification can already begin to unlock some of the powers of a µDIC setup at minimal costs. The M-lite 5M camera has 3.45 µm...

3D / Stereo Configurations StrainMaster µDIC Elimination of Errors caused by Misalignments Whenever the surface to be studied is not completely flat, a stereo 3D DIC system should be used. Even when working with flat samples a stereo 3D configuration can offer significant benefits over 2D. For example, when loading a flat faced sample and measuring displacements and strain with a single camera it is important that the loading direction remains perpendicular to the camera. Any movement of the sample towards or away from the camera cannot be quantified by single camera setup, and as a result may...

Device Control Unit X StrainMaster µDIC Quick and Simple Configuration of the System LaVision‘s flexible Device Control Unit X synchronizes the cameras and lighting together using stable and accurate hardware generated triggers. All the timing options are controlled from within the DaVis software, meaning the user can setup and configure the system quickly and simply requiring minimal parameter input. Often there will be a test machine driving the loads which are imparted on the sample. LaVision‘s system can be configured to trigger images at various points in the loading cycle. The decision...

Illumination Options StrainMaster µDIC Great Variety of Illumination Options When imaging at high magnification the levels of light reflected back to the camera sensor are often lower than for a standard macro setup, and working distances can often be very small. For this reason LaVision offers a number of different illumination options which can be selected to fit with the experiment. Where working distances are not significantly restricted and optical access to illuminate the specimen is good, LaVision‘s linear illumination units offer a very flexible solution. The illumination can be in either...

Testing in Challenging Environments StrainMaster µDIC Solutions for Difficult Optical Access Part of the appeal of using a DIC system is that it can measure strain on surfaces where traditional strain gauging becomes difficult. Some examples include submerged samples, or testing at elevated temperatures. In these environments the normal strain gauge will not survive, and even if it could survive, access to the sample for a mechanical extensometer will be extremely difficult. Top loading system In these cases the sample is often housed in some form of chamber where optical access can be difficult....
