This laser speckle photography system can be used to measure the surface displacement field of an object from its double-exposed speckle graph. Other related parameters that can be measured using the speckle effect include strain, stress field, distance, velocity, internal defect, and internal vibration analysis.
LEOI-26A can be used to conduct the following experiments:
1.Take free-space and imaging speckle patterns to understand laser speckle phenomenon and characteristics
2.Point-to-point analysis of the surface displacement of an object from its double-exposed speckle graph
3.Global analysis of the surface displacement of an object from its double-exposed speckle graph
