- Instrument Introduction
The use of double-exposure speckle patterns to measure in-plane displacement fields on object surfaces, as well as the resulting strain, distance, and velocity measurements, and the analysis of internal defects and vibrations within objects, represent promising application areas for the speckle effect.
- Experiment Details
1. Capture free-space and imaged speckle patterns to understand the laser speckle phenomenon and its characteristics
2. Master methods for measuring in-plane displacement of objects through both point-by-point and full-field analysis of double-exposure speckle patterns
