Speckle interferometry offers the possibility of full field and non contact measurement of displacements and strains. The development of a miniaturized and easy to use laser optical strain sensor based on this principle offers a new range of applications. The analysis of notched titanium alloy specimens can determine the strain distribution around the notches. Strain concentrations as well as uniaxial loads are visualized.
The increasing demand for better characterization of materials and components in many cases requires full field information for the analysis of the mechanical behaviour. Speckle interferometry is known as non contact and full field measuring technique for displacement and strain analysis. New designs of miniaturized and easy to use speckle interferometric measuring systems enable new applications in tensile testing machines.
