LaVision will hold a free webinar on 21 March 2023 on the topic Photogenic Digital Image Correlation (DIC) – The Benefits of an Optimal Image Modality.
Digital Image Correlation (DIC) is an image based technique typically used to measure the deformation and strain of object surfaces during loading. This is achieved through time step correlation of a pattern on the surface of the object. The pattern is typically applied by the experimentalist and thus necessary that it faithfully follows the underlying surface. In addition, it is very advantageous that the image of this pattern is as optimal as possible. This is where photogenic patterning reveals it’s true value.
A photogenic object is one that consistently provides high quality image characteristics through the production of its own light emission (i.e. luminescence subcategories of fluorescence, phosphorescence, etc.), see Figure. A photogenic pattern can be applied without the need for a basecoat thus minimizing the chance of delamination. In addition it does not suffer from specular reflections from underlying surfaces.
The DIC community has not yet fully appreciated these and numerous other benefits offered by photogenic patterning. This webinar will present the principle characteristics of photogenic DIC, required hardware, and a range of application examples.
