Simulation of laser speckle patterns, evaluation with cross-correlation and simulative investigation of a deformation gradients’ influence on the evaluation

Semester: Sommersemester 2021
Course: MSc Produktionstechnik
Suitable as: Master's Project
Group size: 3-3 persons

Speckle photography is an optical measurement method for the high-resolution determination of deformation fields. In this process, the characteristic speckle pattern of a surface is recorded with a camera during a deformation. The evaluation of the images with cross-correlation allows a large-scale detection of smallest deformations in the nanometer range.

The aim of the project is to investigate the influence of deformation gradients on the measurement uncertainty of the calculated displacement fields. For this purpose, speckle patterns will be created and the influence of deformation gradients will be evaluated simulatively. In addition, a validation experiment is to be planned and carried out.
