Abstract

Two digital optical methods to measure micro-deformation field are investigated. One is digital shearography measurement, the other is reflecting digital holography interferometry. Corresponding experiments are done based on both methods mentioned above, and the stripe pattens are gained by using digital image processing. A simple and quick method to interpret stripe pattens is presented and corresponding results are also obtained.
