Resolution for 2024: Better Speckling!
This video covers the fundamentals of creating an effective speckle pattern for digital image correlation. In digital image correlation, one or more cameras take a series of images as a specimen deforms. Measurements are taken by precisely analyzing the position of unique groups of speckles on the surface of the object as it moves through successive images. Using an optimal speckle pattern is one of the most important factors in reducing measurement noise and improving overall DIC results, therefore, understanding the requirements of an ideal speckle pattern and how to apply one to a specimen is a vital part of DIC. In this tutorial, we briefly discuss the theoretical background of DIC, then we’ll cover general speckle pattern requirements and outline some common application methods.
